Vebjørn Isaksen’s art begins from a productive mismatch. Code is exact, but the phenomena that attract him are weathered, irregular, and alive. Sedimentary rock records particles settling through water or air. A tree adds growth rings while responding to seasons and environmental conditions. Isaksen does not reproduce these subjects as illustrations. He abstracts their formative logic, then constructs algorithms capable of producing families of related images. His two AB[500] projects, Strata and Dendro, make this method unusually clear.

A gallery profile identifies Isaksen as an Oslo-based generative artist and former computer scientist whose largely static work combines the structural character of the digital with the relative disorder of the physical world.¹ That biography matters because his practice does not treat programming as a neutral production tool. The algorithm is the compositional field. Isaksen develops it through repeated experimentation, beginning with a basic technique or idea and testing it until something compelling emerges.¹ Such iteration situates authorship not in a single image but in the design, calibration, and limits of a system.

The resulting works possess a notable visual directness. Their sources can be named quickly, yet their behavior cannot be exhausted by the source metaphor. Layers buckle, split, and change direction. Contours gather around displaced centers. Color behaves as both material and signal. Across each edition, a common grammar remains visible while individual outputs disclose the breadth of the generative space.

The accumulated image

Strata was released through Art Blocks on March 11, 2022 as a collection of exactly 650 unique artworks.² Its premise is geological layering. The project account explains that sedimentary strata form as particles settle, while Isaksen’s digital system generates successive colored layers to evoke rock formation.³ The token hash determines the route each output takes through the project’s generative space.³ This distinction is essential: the algorithm does not simply add a texture resembling stone. It stages accumulation as the image’s governing event.

In the ten outputs assembled here, horizontal ordering repeatedly yields to disturbance. Some compositions appear compressed, as if subjected to lateral force. Others open into broad shelves, narrow seams, or cliff-like interruptions. The visual analogy is geological, but the images also recall maps, woven bands, stacked paper, and stratigraphic diagrams. Their ambiguity allows Strata to move between landscape and abstraction without settling fully into either category.

The collection’s documented traits include variables for density, direction, surface, symmetry, palette, outlining, and coloring strategy.⁴ These parameters help account for the series’ range, but a trait list alone cannot describe the perceptual result. Variation is coordinated. A sparse structure exposes the path of individual bands, while a dense one makes layering feel like mass. Outlines sharpen separation; neighboring colors can instead make boundaries vibrate or dissolve. Symmetry may establish monumental stability, only for directional changes to introduce pressure and drift.

Strata is most convincing when geology is understood not as subject matter alone, but as a model for how an image acquires time.

The project also crossed deliberately from screen to paper. Kate Vass Galerie offered token holders the opportunity to request a single signed print associated with an individual output, produced on Hahnemühle Photo Rag paper in one of two formats.³ The gallery stipulated that only one such print would be made for a token.³ This arrangement extends the project’s concern with uniqueness into physical circulation. The printed surface does not replace the computational work. It gives the generated layers weight, scale, ink, and texture.

Controlled chaos before and beyond Strata

An earlier work, OBSTACLES, clarifies the importance of bounded disorder to Isaksen’s practice. The composition uses an underlying isometric grid and a coordinate-based placement system to arrange objects of differing height, length, and depth.⁵ Isaksen described its governing idea as “controlled chaos,” with a frame enclosing randomized colors, variable transparency, and occasional outlines.⁵ The phrase is an effective key to Strata as well. Randomness produces difference, but only within an authored architecture of relations.

The artist’s participation in the gallery exhibition PHYGITAL further placed his work in a conversation between computational generation and material presentation. The exhibition brought contemporary generative artists together with historical computer-art figures including Harold Cohen and Hans Dehlinger, and presented Isaksen among its participating artists.⁶ The gallery’s exhibition archive dates the show from April 8 to September 1, 2022.⁷ Its framework is pertinent because Isaksen’s images consistently test how computational structures register differently as emitted light and deposited ink.

His inclusion in the 2023 Koami Art Festival likewise situated the work within a wider discussion of digitalized art and automated markets. The festival combined a virtual gallery, streamed talks, performances, and interactive environments, listing Isaksen among an international group of contributing artists.⁸ These appearances show a practice circulating through formats that range from browser-native generation to physical print and virtual exhibition space, without requiring the image to abandon its algorithmic origin.

Growth directed inward

Dendro comprises exactly 275 artworks. OpenSea’s collection record associates the project with Art Blocks and records its May 2023 launch and supply.⁹ Its conceptual anchor is dendrochronology’s most familiar visual evidence, the rings through which a tree records growth. Yet Isaksen alters the expected circular image. The project description states that the algorithm begins with the outermost ring and grows inward toward an arbitrarily selected center, adding forms inside previous forms according to rules and parameters.¹⁰

That reversal changes the temporal intuition of the work. A biological trunk expands outward, but Dendro computationally works toward an interior destination. Growth becomes excavation. The image appears to search for its own center, which may be stable, displaced, fragmented, or visually contested. Noise and geometric variation pull the rings away from naturalistic circles and ovals, while mutations interrupt smooth continuity.¹⁰ The natural process supplies a grammar, not a template.

The palette follows the same principle. Rather than confining the system to realistic bark and earth tones, Isaksen drew color from the perceived richness of the natural world.¹⁰ This permits sharp chromatic contrasts and synthetic harmonies while retaining the project’s organic proposition. Traits documented for the collection include background, brush, brush weight, canvas, density, edges, fragmentation, margin, palette, and coloring strategy.⁹ These variables govern not only appearance but the apparent temperament of each virtual organism.

Where Strata often stretches time laterally across a field, Dendro concentrates it around a center. The former can resemble a cross-section cut through terrain; the latter behaves like an eccentric record of duration. Both translate incremental natural formation into repeated computational operations. Both also rely on noise to prevent the system from becoming diagrammatically inert. The comparison demonstrates Isaksen’s recurring interest in processes that are ordered in principle but irregular in manifestation.

The system as a way of seeing

Isaksen’s natural references should not be mistaken for a retreat from technology. Rather, they allow him to ask what code can perceive about formation. Geological strata and tree rings are already records. Each stores the effects of duration, pressure, interruption, and environment in visible structure. By choosing such subjects, Isaksen establishes an analogy between natural inscription and generative output: both make histories legible through accumulated marks.

This analogy also exposes a productive limit. A token hash does not reproduce the environmental causes that shape stone or wood. It initiates a deterministic computational sequence designed to yield a persuasive visual event. The artistry lies in the conversion between domains, from settling matter to colored layers, from seasonal growth to nested contours. Isaksen preserves enough of the source process to make it intelligible, then introduces sufficient geometric and chromatic freedom to keep the result from becoming simulation.

Across 650 editions of Strata and 275 editions of Dendro, repetition therefore functions critically. No single output defines either work. The collection is the proper scale at which the algorithm becomes visible, because similarities reveal its rules and differences reveal its reach. Market and archive pages can enumerate supply, traits, ownership, and transaction histories,⁴⁹ but the aesthetic achievement resides in the tension among these many outputs. Each image is complete, while also acting as evidence of a larger possibility space.

Isaksen’s earlier professional formation provides another context for this disciplined system building. The ACL Anthology records his co-authorship of a 2020 paper evaluating transfer-based language models for detecting hateful and offensive language online.¹¹ The research belongs to a different domain, but it confirms sustained engagement with computational models, classification, and the gap between formal systems and complicated real-world phenomena. In the artwork, that gap becomes generative rather than merely technical.

Isaksen’s contribution to generative art is grounded in the patient construction of systems that look back toward material processes. His algorithms do not erase nature’s irregularity in the name of computational order. They make order porous to variation. In Strata, layers become compressed histories of settling and pressure. In Dendro, contours become an inward-growing record of virtual life. Together, the works propose code as a means of attending to how forms accumulate, mutate, and endure.
