Cat roombas

Named after a roomba script that slowly crawls around the canvas.

A colorful, pulsating cat whose movement seems to be restricted to cells with a black background color (though it can violate this boundary in small increments). Deleting too much of the cat causes it to deactivate, though it has the capacity to regenerate from minor damage.

There was a version of this script that could move freely around the canvas, leaving behind a trail of black cells as it traveled.
