Doomsday was a visual toy created to learn the workings of the Quartz drawing system. It was abandoned a couple years ago, but remains a very powerful example of what quartz can accomplish.

It is unsupported, and many features work erratically or are totally unimplemented. We are providing it solely as a demo.

Doomsday can emulate all the basic motions of clock, but allows for many other types of behavior based a number of variables.
