Placement

The work and its context

Placement makes colour relationships conspicuous by giving them a firm geometric setting. Rectangles contain other rectangles, borders exchange colours with interiors, and small neutral marks interrupt otherwise continuous fields. In some outputs the arrangement stands alone within generous empty space. In others it repeats beyond the screen, so the visible image becomes a portion of a larger pattern. The five originals inspected here move between these two scales of attention.¹²³⁴⁵

Cooper Jamieson released the 500-work project through Art Blocks Factory in November 2021. Its official description connects the intensity of printed ink with the light of a digital display, presenting code and silkscreen as different means of encountering colour. The page also records an exhibition of six works at the Art Blocks Gallery in Marfa between May and October 2022. The Cooper Jamieson dossier provides wider context for his practice.⁶

The geometry gives the viewer something stable to compare while colour and placement disturb that stability. A pale square can appear to open a hole in a coloured panel, although it is simply another painted area. A repeated frame can become a solid shape when its interior changes. These shifts are readings of the inspected pictures, not claims that the program calculates perceptual depth.¹⁴

Conception and development

Jamieson's June 2021 Art Blocks interview describes a practice formed through both art and chemistry. He studied ceramics and painting, assisted with Robert Irwin's installation at the Chinati Foundation and subsequently worked in conservation. He presents those experiences as a training in looking, then connects his scientific studies to the ways artists formulate and test ideas. This account predates Placement and supplies context rather than a complete development history of its algorithm.⁷

The same interview names his interest in works concerned with the experience of seeing. It also sets out a criterion for generative art: diversity across outputs should coexist with the strength of individual works. That position offers a useful way to approach Placement. The repeated framework can be judged both as a system of variation and as a particular arrangement that must sustain attention on its own.⁷

The project description makes a more specific proposition about the frame. It treats the boundary around colour as a device for concentrating attention, while relating the screen to a printed surface. The code gives that proposition a concrete form through nested rectangles and neutral interruptions. A frame is not merely applied around a finished image; it becomes one of the coloured elements whose role can change within the image.⁶⁸

No dated sequence of sketches or complete account of the program's revisions was recovered for this essay. The deployed source supports analysis of the final decisions, but not a reconstruction of every experiment that preceded them. The relationship to Jamieson's earlier installation and conservation experience is therefore contextual, not a claim that Placement copies a specific Irwin work or translates one named historical painting.

How the work was constructed

Placement uses the browser's two-dimensional canvas directly. The indexed runtime label is js@na, and the inspected artist script contains no import of a separate drawing library. It constructs a canvas, obtains its 2D context and calls drawing functions that fill rectangles or stroke straight segments. The apparent frames and openings are made through the order of these flat marks, rather than through a model of objects in three-dimensional space.⁹⁸

The token hash is converted to bytes and mixed twice with different initial values. Those results initialise a pseudorandom generator whose state is stored in four sixteen-bit words. The generator selects a group of parameters before the drawing function is returned. The selection establishes the colours, layout and additional marks for the output; it is not repeated every time the browser repaints the canvas.⁸

Colour comes from an ordered array of fifty-five hexadecimal values. A selected index gives access to neighbouring entries, and the drawing branches distribute those neighbours among outer and inner rectangles. This structure means that adjacency in the stored palette list is itself a compositional decision. The program does not freely sample every red, green and blue channel. A separate choice establishes a pale or dark neutral ground, with its opposite available for contrasting marks.⁸

The geometry is organised around a shared module derived from the smaller viewing dimension. Basic functions place one rectangle inside another, using landscape or portrait proportions. Other functions arrange two such units vertically or horizontally. Eight layout branches select among these arrangements, combine them or extend them into repeated fields. Some loops draw units well beyond the visible area, allowing the viewport to crop a larger repetition.⁸

Further selectors introduce neutral bars, squares, partial outlines and areas that cover earlier colour. These additions can divide an interior, interrupt a border or make an opening appear to continue into the ground. Their logic depends on both placement and drawing order. An opaque rectangle painted late can look like a cutout without removing any of the pixels beneath it. This distinction is useful when reading the work's apparent front and back.⁸

The line width scales separately from the larger geometric module. Fine segments can therefore articulate the edges of broad colour areas without becoming another equally heavy panel. Related layouts also change which neutral colour occupies a given position. The same small square can register as a bright interruption or a dark recess according to the surrounding field.⁸

The output is static. A window-resize listener updates the canvas dimensions, accounts for device pixel ratio and invokes the same drawing closure again. Because the selected parameters remain outside that closure, resizing changes the drawing dimensions while preserving its underlying choices. The script contains no continuous animation loop, sound routine or pointer control beyond the browser's resize event. These source findings explain the fixed compositions inspected in the five original views below.⁸

The mint

The current Art Blocks index records 500 invocations and a maximum of 500. Its first token was minted on 4 November 2021, before activation on 13 November and the scheduled public start on 19 November. The platform's collection page gives 19 November as the release date. The earlier token and the release date concern different events, and the early recipient's allocation role has not been established here.⁶⁹⁸

The scheduled-start field reads 17:00 on 19 November. The second mint is recorded at 17:01:32, with sampled editions 10 and 20 following at 17:02:57 and 17:03:24. Edition 157 was minted the next day. These observations provide a small set of dated anchors; they are not a complete transaction history or a record of each participant's purchase price.⁹⁸

Completion is recorded on 10 May 2022, substantially later than the release. The index alone does not explain that interval. It could contain changes of sale state or other circumstances that require historical evidence, so this essay does not describe it as one continuous public sale. Nor does the completion field establish that the later Marfa exhibition caused the remaining mints.⁹

The current price setting is 0.1 ETH, and the retrieved sales-notes field is empty. That setting is retained as a present configuration observation. An original announcement or transaction reconstruction is still needed before asserting the opening price or the amount paid for any specific token. Current supply, release date and price setting answer different questions and should remain separate.⁹

Copyright and licensing

The artwork record reports CC BY-NC-SA without a version number and provides no terms link. This essay preserves that exact label. It does not substitute the 4.0 deed merely because that version is familiar. A project-linked licence statement is needed to establish the intended version and any earlier terms.⁹

No separate grant for the complete artist script was identified in the inspected source. Its concluding acknowledgements name several people but do not define their contributions or provide a software licence. Readable source and public display are not themselves evidence of an unrestricted reuse grant. The script remains in the private research cache rather than being redistributed with the essay.⁸

The inspected renderer uses native browser Canvas 2D operations and contains no imported third-party drawing library. The browser remains part of the rendering environment, but there is no p5.js or three.js licence to assign to this particular artist script. AB5D's CC0 dedication covers the original prose, separately from the artwork and code rights.⁸

Close reading of examples

The sample comprises editions 0, 1, 10 and 20, plus verified AB5D collection example 157. Their full token identifiers are 205000000, 205000001, 205000010, 205000020 and 205000157 on Ethereum contract 0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270. All five official generators were viewed at the same landscape dimensions. This comparison concerns those outputs, not the frequency of their designs across the edition.⁸

Edition #0 places two portrait panels side by side on a pale ground. On the left, a light pink border surrounds a gray interior and a black central square. On the right, a blue border surrounds pink and a pale central square. The panels share their proportions, making the different colour roles unusually easy to compare. Pink moves from an outer boundary to an enclosed field; the central square changes from the darkest part of the image to a colour close to the surrounding ground.¹

That last change unsettles the apparent structure. The black square can seem like a solid insert or a deep recess. The pale square on the right can appear to open through the panel to the ground behind it. Neither interpretation is required by the flat drawing, yet the matched geometry encourages the eye to test them against each other. The wide gap and surrounding space slow the comparison: each panel remains discrete, while their equal dimensions insist on a relationship.¹

Edition #157 fills the viewing area with repeated portrait units in strong blue, red-orange, pale beige and off-white. The edge of the screen cuts through the pattern. Some units have saturated borders and pale interiors; others reverse that distribution. The viewer can follow the repetition laterally, but the colour changes prevent the sequence from becoming one unvarying beat.²

Thin pale horizontal cuts cross alternate panels at different heights. They interrupt both a border and an interior, momentarily joining areas that otherwise seem separate. Broad pale gaps already organise the repeated units, so these finer cuts create a second scale of division within them. Compared with #0, the work feels less like two objects presented for comparison and more like an environment of related surfaces. The same rectangular vocabulary changes its effect when it continues beyond the frame.²

Edition #1 also repeats portrait panels across the screen, here in turquoise and pale gray against a dark field. Heavy dark gaps establish a strong grid. Finer dark lines cross the panels at alternating heights, while larger neutral overprints open portions of their borders. The coexistence of thick divisions and thin cuts makes it difficult to settle on one scale: an individual panel is legible, then absorbed into the larger pattern.³

Edition #10 compresses the arrangement into a central monochrome construction. A gray portrait frame overlaps a wider black rectangle, with black filling the centre. Pale vertical interruptions break the gray frame on both sides. The symmetry is clear, but the apparent layering is less certain. The pale areas can be read as missing sections, and the black interior can merge perceptually with the shape behind it. Colour restraint makes the order of overlap the dominant question.⁴

Edition #20 presents two rows of broad framed rectangles. Most borders are bright yellow, surrounding pale or dark gray fields and paired black-and-white squares. A pale gray border at lower right interrupts the yellow repetition. The central pairs also change their vertical order between rows. The picture therefore has a strong repeated structure with several small reversals, enough to draw attention to neighbouring differences without dissolving the overall rhythm.⁵

Significance and limitations

Placement gives a limited geometry several perceptual jobs. The rectangle can be a frame, an interior, a repeated unit or a late mark that seems to erase part of an earlier one. Those roles depend on neighbouring colours and on where the viewer places attention. The source's explicit drawing order makes the mechanism simple to describe without exhausting the experience of the result.⁸¹⁴

The contrast between isolated arrangements and cropped repetitions is especially consequential. In one, surrounding space encourages comparison between a few discrete panels. In the other, the screen becomes a boundary imposed on a continuing field. The five inspected works show that this change of scale is part of the system's range, alongside colour choice and internal interruption.¹²³⁵

The project is strongest when these economical changes keep the viewer looking at relationships rather than searching for a hidden subject. Its relevance to the archive lies in that specific achievement: a program defines a finite vocabulary, then lets position and colour make its members perceptually unstable. The documented connection between screen and print extends the inquiry to different viewing conditions, although physical prints were not examined for this essay.⁶

Unresolved research questions:

• Recover project development studies and a fuller account of the print process.
• Establish original sale terms and the history behind the completion date.
• Locate the intended version of CC BY-NC-SA and any separate code grant.
• Compare original rendering at different aspect ratios and inspect the physical prints.
