What Is Generative Art?

Generative art is artwork created with the use of an autonomous system — typically code, algorithms, or rules — that makes decisions about the final output. The artist designs the system; the system generates the work.

Unlike traditional art where every stroke is placed by hand, generative art introduces process as the medium. You write rules, constraints, and degrees of freedom. Then you run the system. The output may surprise you. That surprise is the point.

Key Characteristics

• Autonomy: The system operates independently once started.
• Determinism or stochasticity: The same inputs may always produce the same output (deterministic), or randomness may be involved (stochastic).
• Parameters as palette: Color, form, density, rhythm — all become variables.
• Reproducibility: With a seed, any output can be recreated exactly.

A Brief History

Early pioneers include Georg Nees and Frieder Nake (1960s, plotter drawings), Vera Molnár (algorithmic geometry), and Harold Cohen (AARON, an AI drawing system developed from the 1970s onward). The demoscene of the 1980s–90s pushed real-time generative graphics on constrained hardware. Today, tools like Processing, p5.js, TouchDesigner, and shader languages (GLSL) make generative art accessible to anyone with a browser.

How This Daily Artifact Works

1. The seed: The current date (YYYY-MM-DD) is hashed into a 53-bit integer.
2. The RNG: A Mulberry32 PRNG initialized with that seed produces a deterministic stream of numbers in [0,1).
3. Algorithm selection: One of five algorithms is chosen: Waves (sine-band landscapes with a sun), Moons (grid of crescent phases), Ribbons (Bézier curves across the canvas), Mosaic (recursive rectangle subdivision), or Burst (radial ray bursts with rings).
4. Palette selection: One of six curated color palettes is chosen.
5. Title generation: An adjective + noun pair from curated lists, plus a number (e.g., "electric weather no.84").
6. Rendering: The algorithm draws to a 900×1125 canvas. The result is reproducible — same date, same image, forever.

The Five Algorithms

• Waves: Horizontal sine bands stacked vertically. Amplitude, frequency, and phase vary per band. Every 7th band is a major accent line. A sun circle sits in the upper third.
• Moons: A grid of circles. Each shows a crescent phase determined by the RNG. ~5% become full accent circles. Tiny stars scatter the background.
• Ribbons: 5–9 thick Bézier curves spanning left to right. Round caps, varying opacity. Colors alternate between ink, mid-tone, and accent. Small dots scatter along paths.
• Mosaic: Recursive rectangle subdivision (Mondrian-style). Random splits with gutters. Leaves get fill (accent, mid, or stroked ink). Occasional center dots.
• Burst: 100–220 radial rays from an off-center point. Lengths pulse by angle. Dashed concentric rings. Tips occasionally marked with accent dots.

Why Daily? Why Deterministic?

Most generative art tools let you tweak sliders endlessly. That's exploration. But there's something different about a shared, time-bound artifact — one picture for the whole world today, gone tomorrow. It creates scarcity without artificial limits. The seed is the provenance. You don't need a blockchain; the math is the certificate.

Reroll breaks determinism intentionally — it lets you see the adjacent possible. But "Today's" always returns you to the canonical version. The machine remembers what the day actually was.
