The index records 64 invocations against a maximum of 64. It lists the runtime as plain JavaScript (`js@na`), a square aspect ratio, the licence label `NIFTY`, the Factory vertical and a price field of 0.128 ETH [^S01]. Art Blocks now groups it among the \"Art Blocks 500\" and describes it as animated [^S02].\n\nThe mint text is short and playful. It calls the work the \"Last of the 70s Pops, gone but not quite dead 馃懟\", made of \"nothing but black & white groovy patterns, perfect for colouring in\". It adds: \"Some people say the spirits of the 70s haunt these, but that would be ridiculous!\" All primary proceeds were pledged to the Women Who Code non-profit [^S01].\n\nEach output is a square grid of tiles. In every tile a bundle of parallel black lines, separated by white bands, either runs straight across or turns a quarter-circle between two edges. Joined up, the bundles read as one continuous set of tracks, like a 1970s supergraphic [^S01]. The piece is not still. After a minute the program begins to fill its own drawing with colour, so the \"colouring in\" of the description is something the work does to itself (code reading) [^S01].\n\nDaniel Catt describes himself on Art Blocks as a \"Contemporary printmaker + pen plotter artist, based in the UK\" [^S02]. Before his art practice he worked at Flickr, and in January 2025 he rejoined the Flickr Foundation as co-technical lead [^S03]." }, { "id": "conception-and-development", "heading": "Conception and development", "bodyMarkdown": "Ghost closes a four-project family on Art Blocks. Art Blocks dates 70s Pop Series One (256 outputs) to 7 April 2021, the Super Fun Summertime Bonus Pack (64) to 9 May and Series Two (256) to 13 June. Ghost followed on 13 July [^S04][^S01]. Series One set out the method: \"The input is simple, just two tiles, but how they're rotated and placed, that's the magic\" [^S04]. Summertime, like Ghost, gave its primary sales to Women Who Code [^S04].\n\nCatt's newsletters give the design's origin. He calls 70s Pop \"an ongoing art project hosted on ArtBlocks.io\", \"itself based on a pen plot design I was working on\" [^S05]. He explains that \"it's a truchet tile\" [^S05]: a square whose motif joins its neighbours however it is turned. A later issue describes that plotter work as making \"'70s Pop' style multiscale truchet tiles\" [^S06]. The big and quartered tiles in Ghost are that multiscale element (code reading) [^S01].\n\nIn a December 2024 newsletter Catt recalls the sequence: \"One of the very early projects on ArtBlocks was 70s Pop Series One\". Then came Series Two \"and two 'bonus packs'; Summertime and Ghost\" [^S07]. He writes: \"We had an intermission around Halloween for The Series Two 'bonus pack' Ghost\" [^S07]. Each pack had a companion \"airdrop\". Ghost's was Haunted: \"The screen flickers as the VHS reaches the end and starts to automatically rewind\" [^S07]. OpenSea lists \"70s Pop Ghost Haunted\" as 64 items by Rev Dan Catt on its shared storefront contract, launched in August 2021 [^S08]. Neither the July mint nor an August airdrop matches \"around Halloween\" [^S01][^S08].\n\nThe black-and-white start has a clear source in Catt's own account. In a 2020 interview he named Bridget Riley's op art, and her *Kiss* (1961), as a key influence: \"even with just black and white, those two binary colours, something lovely happens\". He added that \"Bridget worked with Black & White for six years before dipping into colour in 1967\" [^S09]. Ghost compresses that history into two minutes: a Riley-like black-and-white field, then colour. The same interview describes his plotter set-up and code \"that then spits out SVG files\" [^S09]. His artist statement gives the drawing machine \"the role of creator\" [^S10].\n\nThe design has since left the screen. Catt writes that he has \"explored the design with print, screen print, riso print, sculpture, fabric, clothing, pen plotting (of course) and even furniture design\" [^S07]. No source found documents a plotted or printed Ghost output specifically." }, { "id": "how-the-work-was-constructed", "heading": "How the work was constructed", "bodyMarkdown": "The program is a single script of 9,079 bytes, SHA-256 `7e9fe5b877b77cff97fc0afd0acf30334c4be177c264bf50bc9d952009db9290`. It was retrieved from the Art Blocks index on 20 September 2026 and read in full. No code is reproduced here [^S01]. It uses no library, only the browser's 2D canvas.\n\nThe token hash seeds a xorshift random generator from its first 32 hexadecimal characters [^S01]. To test every claim below, the script was run in a stubbed browser environment for all 64 hashes. The reconstructed Tiles, Lines, Format and Boosted values matched the published traits for all 61 tokens that carry traits (own computation) [^S01].\n\n**Grid and lines.** Two random numbers set the number of tiles across the grid and the number of lines in each tile. They pull in opposite directions: across the 64 tokens the correlation between Tiles and Lines is -0.89 (own computation). A few coarse tiles carry many fine lines, and a dense grid carries few thick ones. Separate 10 per cent switches can add two or four tiles, and four more nudge the line count by -1, -2, +1 or +2. Further rules trim lines on dense grids, so that tiles plus lines never exceed 19 [^S01].\n\n**Big and small tiles.** A switch that is on 80 per cent of the time allows double-size tiles covering a two-by-two block. Another allows quarter-size tiles, but only when the line count is even. A grid of fewer than eight tiles never gets big tiles [^S01].\n\n**Format.** If either kind of tile is allowed, a chain of overwriting draws picks a Format, which sets how the chance of big and small tiles changes from row to row [^S01].\n\n| Trait | Rule in the program | Published count of 61 |\n| --- | --- | --- |\n| Format: Top-down / Bottom-up | 9% / about 12.7% when big or small tiles are allowed; big tiles thin out down / up the grid | 6 / 13 |\n| Format: Middle / Outer | about 16.4% / 17.9%; big tiles gather at the centre rows / the top and bottom rows | 9 / 8 |\n| Format: Normal | the remainder; uniform random chances | 25 |\n| Boosted | the net line adjustment, -2 to +2 | 0: 42; +2: 7; -2: 5; -1: 4; +1: 3 |\n| Tiles | 4 to 11, plus 0, 2, 4 or 6 | 4 to 13; 7 is most common (12) |\n| Lines | 3 to 17 before trimming | 4 to 14; 14 appears once (#31) |\n\nThe percentages are computed from the program's thresholds, and the counts come from the index [^S01].\n\n**Drawing.** Each tile, or each quarter of a subdivided tile, gets one of six shapes: two straight orientations and four quarter-circle orientations. The quarter-circles are drawn in facing pairs from opposite corners, the two-tile truchet motif of Series One [^S01][^S04]. The black lines have round caps, over white bands that mask what lies underneath. The canvas takes the smaller of the window's width and height and is scaled for high-density displays [^S01].\n\n**The animation.** The program keeps a list of 35 colours in HSL, of which 25 are distinct, and picks two for the token [^S01]. The black-and-white drawing is shown for 60 seconds. Colour then grows out of the corners of each arc and across each straight tile over the next 60 seconds. The program then generates a fresh tiling from the continuing random stream, stepping 13 and 17 places through the colour list for new colours [^S01]. After six cycles it returns to the original black-and-white drawing (code reading). A double-click shortens the transition and pause to 5 and 2 seconds; a second restores them [^S01]. The whole sequence is fixed by the hash, but only the first drawing appears in a still render (code reading)." }, { "id": "quirks-in-the-algorithm", "heading": "Quirks in the algorithm", "bodyMarkdown": "A full read of the program, checked against a re-run of all 64 hashes, turned up the following.\n\n1. **Three tokens have no traits.** Invocations #1, #2 and #3, all minted in the first second of the public sale, carry an empty feature set, so \"Haunted: True\" appears 61 times, not 64 [^S01]. Re-running their hashes gives #1 as an 8-tile, 11-line Normal; #2 as a 9-tile, 7-line Outer; and #3 as a 7-tile, 12-line Normal (own computation).\n2. **Most published traits are not in the script.** The program computes only Tiles, Lines, Format and the line boost. \"Haunted\" is a constant. \"Underlying Dread\" and \"Paranormal Activity\" track the number of big and small tiles in the first drawing. Low has at most 6 big tiles, Medium 7 to 11, High 13 to 15 and Very High 17 or 18. \"None\" means no small tiles, Latent 2 to 23, Unnerving 33 to 49 and Intense 70 or more (own computation) [^S01]. The cut-offs are not in the script and were presumably applied by a separate feature script.\n3. **The labels count, they do not measure.** Because the ghost traits count tiles rather than share of the grid, #60 is \"Latent\" even though 23 of its 25 cells are subdivided, and #19 is only \"Unnerving\" with 48 of 121 (own computation) [^S01].\n4. **Gradients that collapse.** In Top-down and Bottom-up formats the chance of small tiles mirrors the chance of big ones. When big tiles are off, the mirror becomes a constant 90 per cent, giving a near-uniform field of small tiles [^S01]. This happens in #20 (78 of 81 cells subdivided), #57, #60 and #63, and it is how #20 became one of the two \"Intense\" outputs (own computation).\n5. **Ten Formats that do nothing.** The Format is drawn before the rule that strips big tiles from small grids. In ten tokens (#0, #4, #6, #17, #21, #26, #30, #48, #50 and #51) the published Bottom-up, Middle or Outer has neither big nor small tiles to steer (own computation) [^S01].\n6. **Dead code.** The program fills a list of 275 random numbers it never reads. It tests for a \"Flat\" fill that is never set, so two branches can never run. It checks a per-tile \"next action\" timer that is never assigned, so the tile-by-tile shape cycling it describes never happens. It also computes a half-transparent fill colour it never uses (code reading) [^S01].\n7. **Black and white in the colour list.** The first two colours in the list are black and white. Ten tokens start their colour cycle with one of them. In #24, #36, #37, #43 and #44 one fill is white, invisible on the white ground. The stepping arithmetic means black can only occur as a starting colour (code reading) [^S01].\n8. **A missing bracket.** In the colour pass for straight tiles, the call that closes the rectangle's path is named but not called. The fill still closes, but the outline of a fully coloured straight tile omits its last edge (code reading) [^S01]." }, { "id": "the-most-coveted-variants", "heading": "The most coveted variants", "bodyMarkdown": "No collector commentary specific to Ghost was found.
