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

// BLIMP — a fat video airship cruising a slow bounded figure through the
|
|
// frame: a horizontal capsule whose hull wraps the clip end to end, drifting
|
|
// on three detuned sines with a gentle nose wobble, the beat breathing a
|
|
// little extra light along the belly. Pattern taught here: a fixed axis
|
|
// spin (quarter-turn about z lays the capsule flat) composed with a wobble,
|
|
// and a drift path that is three sines — bounded forever.
