// 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.
