Catclock is originally a X10 program by Tony Della Fera, Dave Mankins, Ed Moy, Deanna Hohn and Philip Schneider, crafted for entertainment, in the late 1980's. It was also ported to the Plan 9 operating system by Tom Duff, which is where I first came across the catclock.
Catclock inspired from the original X10 application.
This Uxntal implementation of the catclock was created in collaboration with Rekka Bellum.
