Spatial 3D

A raymarched glass prism on black: a white beam comes in from wherever your pointer is, a spectrum fans out the other side, and the prism turns once a minute. One shader, no libraries.

A rotating word wheel built on a real cylinder — derived radius, accumulated rotation, no backwards spin on the wrap.

A carousel whose side cards recede in scale, blur and rotation from one offset value.

Words on a rotating cylinder, with the radius derived from the face count.

Cards mounted on a rotating 3D ring — the active one faces forward, others recede.
