Squashed from work; the fine-grained history is under tag archive/work-2026-08-26: - vjfx: 104 new presets — the transition lane fills out and the screen family goes wide - vjfx: three lanes land — engine hooks + hold stage, the videomesh engine, and the audio picture - vj: the thumbnail pipeline becomes one honest machine, and effects go livecodable - vj: thumbnails become mp4 — hardware-coded sheets at measured-4K cells, and the bake stops racing the GPU - store: the ceremony dies — batch publish, one transaction, and the engine stops re-reading its own log - store: the ceremony dies — batch publish, one transaction, and the engine stops re-reading its own log - vj: the console grows real transports, and the deck stops lying about reverse - vj: reverse earns a memory, and the effects stop aging - fab: a 3D creation shell and the viewer built on it

// SPIN CUBE — the live video wrapped onto one big, slowly tumbling cube:
|
|
// every face plays the clip, the silhouette drifts on a tilted axis and the
|
|
// face edges flash on the beat. Pattern taught here: the videomesh engine's
|
|
// placement hooks — fx_axis pins the tumble axis, fx_place composes a steady
|
|
// spin with a slow breathing wobble (both pure functions of time), and the
|
|
// engine's orbit camera does the rest.
