# Twenty more scenes

The library sat at 42 — seven per family, evenly. Even spread is not the same as
useful spread: casting in `look/Personality.js` disqualifies any scene that does
not honour *all* of the track's signature traits, so the pool a given track draws
from is much smaller than the shelf count suggests. `space` and `shape` are the
thin traits, and they are where a new scene is worth most.

So: twenty scenes, roughly three or four per family, weighted towards `space`
(8 of 20) and `shape` (7 of 20), and each one written against a named neighbour
it must not look like. That second column is the real spec — "no two scenes
render the same image" is a gate with a numeric floor, and a scene that cannot
say what it is *instead of* does not exist yet.

Procedure per scene is `.claude/skills/build-visualizer/`: scaffold, write the
`scene()` body, `npm run lint:scenes`, `checks.html?scene=…`, then the full suite
before the batch commit.

## flow

| # | scene | traits | what it is | not like |
|---|---|---|---|---|
| 1 | Rain Column | camera, space, style | falling sheets of rain in depth layers, sheared by wind | Smoke Column rises and diffuses; this falls and stays discrete |
| 2 | Magnet Lines | shape, camera, style | iron-filing field lines around drifting poles | Curl Flow advects noise; here the field is solved, not sampled |
| 3 | Kármán Street | shape, camera, space, style | vortices shedding off a fixed body, drifting downstream | Vortex Drift spins the whole frame; this has one still obstacle and a wake |

## organic

| # | scene | traits | what it is | not like |
|---|---|---|---|---|
| 4 | Turing Bloom | camera, style | reaction–diffusion spots and stripes, grown in feedback | Ink Bleed spreads and stops; this reaches a living equilibrium |
| 5 | Mycelium Web | camera, space, style | threads creeping over a dark substrate, nodes lighting where they meet | Flora grows upright and symmetric; this is flat, branching and lateral |
| 6 | Scale Mosaic | shape, camera, style | phyllotaxis of overlapping scales, breathing | Cell Divide splits; this tiles a surface that never divides |

## minimal

| # | scene | traits | what it is | not like |
|---|---|---|---|---|
| 7 | Pendulum Trace | camera, style | one harmonograph curve drawn into a slowly decaying trail | Silk Ribbon is a wide ribbon; this is a single hairline and its ghost |
| 8 | Contour Map | camera, space, style | sparse topographic contours of a slow height field | Horizon Lines is a parallel bundle; contours are closed and nested |
| 9 | Shoji Grid | shape, camera, style | backlit paper panels with the signature form cut out of them | Moiré Grid interferes; this has four or five panels and holds still |
| 10 | Balance Stack | shape, camera, space, style | a few forms stacked on a horizon, long shadows | Salt Flat has one distant object; this one is near and about to fall |

## structural

| # | scene | traits | what it is | not like |
|---|---|---|---|---|
| 11 | Suspension Span | shape, camera, space, style | cable curves and towers passing overhead | Girder Lattice is a truss field; this is two curves and a rhythm of hangers |
| 12 | Stairwell Descent | camera, space, style | a recursive stairwell seen straight down | Gate Corridor moves through gates; this falls through floors |
| 13 | Aqueduct March | shape, camera, space, style | receding arches, tiered | Pylon Grid is open frames; arches are solid and carry a skyline |
| 14 | Data Aisle | camera, space, style | two racks of indicators receding to a vanishing point | Neon City is exterior and vast; this is interior and close |

## geometric

| # | scene | traits | what it is | not like |
|---|---|---|---|---|
| 15 | Voronoi Shatter | camera, style | drifting Voronoi cells, edges lit, re-seeding on phrase lines | Truchet Fold is a regular grid; these cells are irregular and move |
| 16 | Apollonian Gasket | camera, style | circle-inversion packing, infinitely nested | Quasicrystal is additive interference; this is exact recursive geometry |
| 17 | Isometric Blocks | shape, camera, style | an isometric field of extruded blocks rising on band energy | Floating Geometry drifts free; this is a solid, gridded, lit surface |

## glitch

| # | scene | traits | what it is | not like |
|---|---|---|---|---|
| 18 | Halftone Misprint | camera, style | CMY halftone screens, misregistered | nothing else in the library draws dots |
| 19 | Droste Feedback | camera, style | recursive zoom-and-rotate video feedback around a small motif | Time Smear translates; this scales, so the image eats itself |
| 20 | Analog Wow | camera, style | tape warp: horizontal wobble, chroma bleed, dropout streaks | Scan Tear and Block Mosh are quantised and blocky; this is continuous and wet |
