Info
What it is
In a carved stone arch a bronze cocoon unfolds into a stained-glass butterfly with dark raised lead lines and eight jewel colours in mottled, mouth-blown panes. The wings spread, then the same panes rearrange into a round rose window, and coloured light from the glass is projected onto the stone floor below. It folds back into the cocoon, so the 8 seconds loop. The film has no settings.
Reuse it in your own idea
- Transformation story: cocoon, butterfly, rose window in one 8-second shot.
- Seamless loop: it folds back to the cocoon, so it repeats for any length.
- Spring greeting: the open butterfly holds for a second or two, which suits a short message.
Which part is reusable
src/stained-butterfly.js is the ingredient your AI reuses. demo.js is only the example scene around it, and uses the demo harness only for the demo.
Good to know
- The film is finished: it has no settings. To change colours or timing, edit the shader.
- It is composed for a 4:5 portrait frame.
- Its length is fixed at 8 seconds; repeat the loop to fill a longer clip.

- How it fits a scene
Coordinates: Composed for a 4:5 portrait frame and measured by the frame height: in a wider frame the picture stays centred at full height and its background fills the sides; in a narrower one, such as 9:16, the sides are cropped.
Lighting: Light passes through the glass: the panes glow from behind and project coloured light onto the stone floor.
Timing: The cocoon unfolds into a butterfly, the panes become a rose window, then everything folds back into the cocoon.
- Output
- 1080×1350, 30 fps, 8 s · procedural (computed from the frame number) · seamless loop — Every part of the film is a function of the time modulo its length, and every motion completes whole cycles, so the last frame meets the first.
- Tested
- Rendered 240 frames on 2026-10-10 in Chrome 154.0.8037.97 headless on Linux 7.0.0-38-generic (x64), Node 22.14.0 (WebGL 2 via SwiftShader (software)). Same frame twice from fresh pages: identical. Loop: Frame 0 vs end state (progress 1): mean |Δ| 0.0000, max |Δ| 0 of 255.
- Performance
- One full-screen fragment shader. About 4 ms a frame at 1080 by 1350 on an integrated Intel GPU (Iris Xe), and about 1 s a frame with software WebGL. Plays at 30 frames a second at full size on an integrated GPU.

- Provenance
- From the owner's collection Twenty Impossible Worlds: the original GLSL ES 3.00 shader of the film “Cathedral of a Butterfly”, created with ChatGPT / Codex and used as published, wrapped for AI Pixel Wizard as a three.js full-screen shader in October 2026. The collection's synthesised soundtrack is not part of this ingredient.
