Gerard Ferrandez came to generative art through programming rather than formal artistic training. An early familiarity with 8-bit home computers led him to write games and publish type-in program listings for computer magazines, an experience that joined visual invention to the material constraints of code. He later became an IT manager in the aerospace industry while maintaining a sustained creative-coding practice in Toulouse. Art Blocks describes him as a self-taught generative artist whose algorithmic systems grew from this longer technical history.¹ A 2019 HackerRank interview had already identified him as an influential CodePen contributor, demonstrating that his public reputation preceded his entry into blockchain-based art.²

This history matters because Ferrandez does not treat code as an invisible production aid. Code is the medium through which forms acquire rules, limits, agency, and duration. In conversation with Jeff Davis, he described an empirical process of trying, failing, and modifying until the program began to suggest directions he had not predicted. He consequently located creativity not only in establishing an initial idea but also in recognizing which computational accidents should remain.³ That position gives his practice a distinctive tension: the artist authors the conditions, yet the finished system must retain enough autonomy to surprise both maker and viewer.

Ferrandez’s works are not illustrations of algorithms. They are staged negotiations between rules and emergent form.

From browser experiment to on-chain system

Ferrandez’s earlier practice centered on real-time browser demonstrations, interactive animation, and openly inspectable code. HackerRank’s profile emphasized the intersection of programming, design, and art in his work, while an older software-directory record documents his distribution of Dynamic HTML experiments as early as 2004.²⁴ These contexts encouraged short feedback loops: a visual proposition could be coded, tested, shared, adapted, and refined. Other CodePen users’ documented recreations and adaptations of works such as never force and Metaballs show how those experiments circulated as technical and aesthetic references within creative-coding communities.⁵⁶

By 2021, Ferrandez had also moved toward static SVG compositions for an AxiDraw pen plotter and toward WebGL, whose GPU-level processing supported more complex real-time scenes.³ His transition to Art Blocks therefore did not represent a sudden conversion from conventional studio production to digital art. It extended a mature browser practice into a setting where an algorithm, a transaction hash, and a collector’s act of minting jointly determine an edition.

Ignition crystallized that transition. Released through Art Blocks Curated on January 8, 2021, it consists of exactly 512 editions.⁷ Ferrandez based the work on context-free grammar rules, developing a JavaScript ecosystem in which native objects direct the recursive assembly of cubic and pyramidal structures.³ The resulting objects resemble satellites, vessels, monuments, or machines without settling into a single category. Their science-fiction associations arise from construction rather than narrative illustration: repeated modules become bodies, gaps become apertures, and projected rays turn geometry into an emissive event.

The work is also interactive. Its live rendering permits the viewer to propel the object, alter the zoom, and switch its beams, while hash-selected traits govern structural spacing, geometry, lighting, and day or night presentation.³ These mechanics establish several levels of authorship. Ferrandez defines the grammar and interaction model, the token hash selects a particular configuration, and the viewer temporarily composes its orientation and illumination. The ZKM exhibition CryptoArt placed examples from both Ignition and R3sonance within an institutional account of blockchain art in 2021, confirming the early museum visibility of this body of work.⁸

Resonant fields and imagined cities

Ferrandez’s three Playground projects extend the spatial questions of Ignition while refusing a single signature composition. Utopia, released February 7, 2021 in exactly 256 editions, builds city-like structures whose attributes include temporal setting, sky color, and architectural type.⁹¹⁰ Its title invites an urban reading, but the generated environments remain deliberately uninhabited. Towers, slabs, bridges, and horizons operate as signs of settlement without supplying a fixed society or story. Perspective becomes the organizing intelligence. The viewer encounters not a mapped city but an algorithmic proposition about density, elevation, atmosphere, and the desire to project collective life into architectural form.

R3sonance, released February 28, 2021 in exactly 512 editions, turns toward a more concentrated interaction of repeated structure and optical vibration.¹¹ Its substituted numeral, “3” for “e,” can be read as a nod to the three-dimensional computational space that Ferrandez repeatedly explores. The series can be understood as a study in how repetition becomes affective. Modules do not merely accumulate; their intervals, alignments, and luminous contrasts generate a visual frequency. The ZKM presentation of R3sonance #440 and R3sonance #56 alongside several Ignition outputs made that continuity legible: both projects use articulated geometry to transform a screen into an unstable spatial field.⁸

Aurora as a culminating experiment

Aurora IV, released through Art Blocks Playground on April 24, 2021, is the smallest of Ferrandez’s four AB[500] collections, comprising exactly 128 editions.¹⁴ The reduced edition count gives the series a different cadence from the broad combinatorial surveys of Ignition and R3sonance. Its title evokes luminous atmospheric phenomena while the Roman numeral positions the work within an iterative sequence, suggesting that a generative idea is not exhausted by one implementation but can be revisited through altered rules and technical capacities.

Across all four collections, light is less a finishing effect than a structural agent. In Ignition, rays announce an internal source of energy. In Utopia, illumination distinguishes atmosphere and time. In R3sonance, contrast makes repetition pulse. In Aurora IV, radiance appears to organize the field itself. This approach connects Ferrandez’s experience in real-time graphics with the temporal expectations of interactive art. Even when represented by a still image, each work implies a state within a system rather than a final, singular composition.

Authorship after the rule

Ferrandez’s importance lies partly in how clearly his work exposes the layered authorship of generative art. The artist writes a grammar, but does not draw every form. The hash fixes an output, but does not alone explain its aesthetic coherence. The collector initiates a mint, but does not choose every trait. The viewer manipulates the live work, but cannot escape the system’s boundaries. Authorship is therefore distributed without becoming anonymous. Ferrandez remains present in the decisions that determine how much variation the system can sustain and where randomness must yield to composition.

This balance also explains the works’ relationship to historical computer art. Context-free rules, recursion, constrained variation, and plotted SVGs link his practice to long-standing procedural methods, while browser-native interaction and on-chain generation situate it within a newer technical economy. A 2023 publication on plotter materials listed ge1doot among contemporary practitioners in a lineage of machine drawing, reinforcing the connection between his screen work and physical plotting.¹² Materia’s collection archive, meanwhile, includes Utopia among its generative-art holdings.¹³

Ferrandez’s public code practice remains active. In January 2026, he released Where the Shadows Wait, an open-source browser work that builds a generative city from CFDG-inspired rules and WebGL2 procedural geometry, revealing it through temporal ambient occlusion and soft shadows.¹⁵ The project makes the continuity between his early browser experiments and his current rule-based spatial systems explicit.

The strongest works retain the provisional energy of experiments while achieving the internal discipline of editions. Their recurring spacecraft, towers, matrices, and radiant fields do not resolve into a closed iconography. Instead, they demonstrate how a limited vocabulary can produce persistent difference. Ferrandez’s practice asks a foundational question of generative art: not whether a computer can make images, but how an artist can build a system capable of yielding many images that remain recognizably related, individually compelling, and open to further encounter.
