How it works
Every frame a triangular wedge is clipped from the current source, mirrored, and repeated radially — only the source moves, the outer composition never rotates as a whole. Load a track and its tempo is detected offline, then the beat grid runs off the track's own clock: the motion loop is a whole number of beats, each beat adds a decaying punch scaled by the live bass energy, and the image sequence hands over to the next source on the beat you choose.
