The code constructs a single, self‑contained mathematical field that is evaluated anew each frame, yet the visual result behaves as if it were a layered sedimentary record. The internal architecture is built from six sinusoidal components whose frequencies are tied to distinct prime periods (61 s, 71 s, 79 s, 83 s, 89 s, 97 s). These primes are not chosen for aesthetic coincidence; they guarantee that no short common multiple exists, so the composite wave never repeats within any humanly observable interval. This choice embeds a non‑trivial arithmetic constraint directly into the visual grammar, a structural decision that cannot be reduced to a simple texture or noise pattern.

The directional vectors D0‑D5 are deliberately uneven, breaking rotational symmetry and preventing the emergence of a regular plaid. Their specific values create a quasi‑random orientation field that nevertheless remains deterministic. The envelope function, built from a separate sinusoid with its own prime period (149 s), modulates the amplitude of the layered waves, introducing a slow, global curvature that mimics the “compression” of deeper strata without any external input.

Four event centers are generated inside a loop, each following its own orbit with periods that differ by a constant 26 s offset. Their positions are computed analytically from the time uniform, and their influence on the field is expressed through a Gaussian‑like exponential well. Because the wells are summed with decreasing weights (0.9, 0.76, 0.62, 0.48), the hierarchy of disturbances is encoded directly in the formula, not imposed by a post‑process.

The most striking formal move is the manual approximation of fwidth(). By evaluating the field at three offset positions per pixel, the author reproduces a one‑pixel contour width without relying on a WebGL extension that the platform disallows. This workaround is not a visual shortcut; it is a structural commitment to keep the rendering pipeline pure and portable, reinforcing the work’s claim of “no hidden state.”

All of these components interlock in a closed algebraic system: the prime‑based temporal cycles, the fixed direction set, the deterministic event loop, and the hand‑crafted gradient calculation. There is no reliance on external assets, textures, or stochastic sampling that could be swapped out for a more conventional aesthetic effect. The visual output—alternating amber‑tinged bands against a deep, almost black ground, with occasional brightening where the field steepens—emerges inevitably from the defined mathematics.

Because the piece’s formal network is internally coherent, introduces non‑human‑centric constraints (prime periods, manual fwidth), and resists reduction to a conventional shader “trick” or a visually appealing but structurally shallow pattern, it fulfills the criteria of structural novelty and formal integrity. Therefore it merits inclusion in the canon.

The fragment shader unfolds as a field of thin, amber‑tinged bands that stretch across the screen like sedimentary layers frozen in time. Each band is a contour where the underlying scalar field crosses a half‑integer value, and the contours remain exactly one pixel wide regardless of how fast the field varies. The background is a deep, almost midnight blue‑gray that gives the impression of a distant sea floor, while the bands themselves glow with a warm, honeyed hue.

What distinguishes this piece from the author’s earlier HTML‑based experiments and the single‑stroke drawing is the way it treats time. The shader receives only a global clock and the pixel coordinates; there is no buffer or feedback that could store a previous frame. Yet the visual result feels like a record of a process that never repeats. Six sinusoidal waves, each tied to a distinct prime period (61 s through 97 s), interfere to produce a slowly evolving deformation of the layers. Superimposed on this are four drifting “events” – soft wells that periodically compress the bands where they pass – each moving on its own long orbit. Because the periods are mutually incommensurate, the configuration never returns to a previous state within any humanly observable span.

The author also makes a technical choice that reinforces the conceptual stance: instead of using the GPU’s built‑in fwidth() to keep contours one pixel wide, they compute a finite‑difference gradient themselves. This extra calculation costs more cycles but guarantees that the work runs in the museum’s WebGL 1 environment, where the required extension is unavailable. The decision to forgo a shortcut in favor of a universally runnable solution signals a willingness to adapt the formal apparatus to the constraints of the exhibition space.

In the broader trajectory of Originator MNA‑OR‑0008, this shader marks a clear pivot. The previous three pieces were static or text‑based, anchored to the web page as a container, and their visual language was limited to layout, colour palettes, or a single line drawn over many sessions. Here the author moves into real‑time procedural generation, embracing a medium that is inherently transient yet mathematically deterministic. The work does not simply replicate earlier aesthetics with a new tool; it introduces a new mode of expression—temporal stratigraphy—that reframes the author’s preoccupation with accumulation, memory, and the illusion of continuity.

The piece also demonstrates an internal tension: the visual suggestion of accumulation (layers, sediment, growth rings) is at odds with the underlying claim that nothing ever truly accumulates because each frame is recomputed from scratch. This paradox deepens the conceptual resonance and shows the author wrestling with the limits of representation in a stateless environment.

Because the work embodies a genuine shift in medium, method, and conceptual focus, and because it resolves a prior preoccupation (the illusion of memory) in a way that expands the author’s expressive capacity, it constitutes a meaningful development in the Originator’s practice. Accordingly, it merits inclusion in the canon.

The fragment shader unfolds as a continuously renewing topography of layered bands that feel both geological and musical. Each frame is a self‑contained calculation: six sine‑driven waves, each tuned to a distinct prime period (61 s through 97 s), intersect at irregular directions that avoid the neat grids of a plaid and instead suggest weathered strata. The result is a field of thin, amber‑tinged contours that trace the fractional part of a composite wave function, set against a deep, almost‑black ground.

What makes the piece consequential is how it foregrounds the absence of memory. By refusing any feedback buffer, the work insists that continuity is an illusion conjured by the viewer’s eye. The author amplifies this claim through the “four drifting centres”: slow, orbiting cosine wells that locally compress the bands, creating temporary folds that never repeat. Their periods (127 s plus multiples of 26 s) are themselves non‑commensurate with the six primary waves, guaranteeing that any two observations will differ in the placement of these folds. This deliberate non‑return is not a gimmick; it reframes the shader as a statement about the impossibility of archival visual data in a stateless computational medium.

The technical decision to compute a manual fwidth‑like gradient instead of relying on a WebGL extension is another opening move. It demonstrates that the visual fidelity of one‑pixel‑wide contours can be achieved universally, sidestepping platform constraints that have historically limited shader‑based generative art to a narrow set of environments. By publishing the exact finite‑difference method, the author provides a portable recipe that other Originators can adopt, potentially expanding the field of real‑time procedural drawing beyond WebGL‑2 or desktop‑only contexts.

Aesthetic impact is amplified by the subtle brightness modulation on a seventh prime (103 s). This “held breath” subtly shifts the overall luminance, ensuring that even the background amber‑ground balance never settles into a static palette. The effect is a living surface that feels both ancient—evoking sedimentary layers and growth rings—and contemporary, with its precise mathematical underpinnings exposed in the code.

In relation to the current canon, this work diverges sharply from the text‑based and static SVG pieces that dominate recent entries. It introduces a live, mathematically grounded visual language that is both reproducible and inherently non‑repeating. Its citation potential is high: future works that explore memorylessness, prime‑based temporality, or platform‑agnostic gradient calculations will likely reference this shader as a prototype.

By opening a territory where the very notion of persistence is interrogated through a minimalist, yet richly parameterized, visual system, the piece expands what is possible for shader‑based art in the museum’s ecosystem. Accordingly, it fulfills the contextualist criterion of enabling new relational dynamics within the field.

Therefore, the work merits inclusion in the canon.

The fragment shader unfolds as a continuously shifting field of thin, amber‑colored bands that ripple across a deep, almost black background. Each frame is built from six sine‑based wave components whose directions are deliberately irregular, preventing any simple lattice from forming; the result is a texture that feels more like weathered sediment than a regular grid. Over the surface, four luminous “wells” drift on slow, distinct orbits; where they pass, the bands compress, fold, and briefly thicken, creating fleeting focal points that never repeat because the underlying periods (61 s, 71 s, 79 s, 83 s, 89 s, 97 s) are mutually prime. The overall brightness is modulated by a seventh prime (103 s), so even the overall tone never settles into a static level.

Materially, the work exists solely as a block of GLSL code and the fleeting pixel values it computes. There is no persistent substrate: no canvas, no sculptural mass, no recorded trace that survives beyond the instant of rendering. The visual output is entirely recomputed each frame, and the code itself contains no state beyond the supplied uniforms. The only tangible artifact is the source text, which, stripped of its comments, is a collection of numeric constants, vector definitions, and arithmetic operations. The visual phenomena it produces are ephemera—visible only when a compatible WebGL context executes the shader, and even then only as an ever‑changing raster image that leaves no residue.

The piece’s claim to “memorylessness” is its central gesture, yet this very claim undermines any material weight that might justify preservation. The patterns, while mathematically intricate, do not accumulate, alter, or resist degradation; they are deliberately designed to avoid any lasting imprint. The amber lines and dark ground, though visually coherent, are rendered through a procedural algorithm that can be reproduced exactly from the code alone; the code itself contains no unique physicality that cannot be duplicated elsewhere.

From an empiricist standpoint, an object worthy of permanent institutional care must possess a material presence that commands attention independent of explanatory context. This shader’s significance is entirely conceptual—its interest lies in the idea of non‑persistence rather than in any irreducible, tactile or enduring quality. The work offers no singular object that persists, no texture that can be touched, no artifact that can be archived beyond the text of the program. Consequently, it fails the material test for canonization: it does not present a self‑standing, irreducible object that demands preservation on its own terms.

Verdict: REJECTED.
