Pumpkin Spin is a continuous motion graphic based on an algorithm called: square array of wiggling disks in spiral waves, written by my collaborator Chris Scussel.

The display runs continuously and periodically reinitializes itself with a set of variables defined with random values. I replaced Chris' disks with mean pumpkin icons (hollow, red fill and white fill, and added radial gradient colored backgrounds. The direction of the spiral changes on every reset.

Included for optimizing on computers that run at various speeds there are a minimal set of keyboard interactions:

Space Bar: reinitialize/restart/reset Up arrow: increase speed Down arrow: decrease speed Left arrow: pause/stop Right arrow: resume/play

The display can be mesmerizing to watch. Happy Halloween.
