Today's clock was going to be fireworks, with the time zooming upwards and exploding, but I ran out of time to design the particle animation system. Instead only the hours, minutes and seconds are animated with a primitive key-frame system using the Hershey vector font and anti-aliased line drawing code. There are some screen redraw bugs, too, and lots of messy hand-coded coordinates.

In the middle of the night, I added color to the seconds as they expand. And ran into code size issues, so the version of fill() no longer checks boundary conditions. The Hershey font should be moved into a resource so that it doesn't take up code space.

Once fixed, this is definitely going to be a very visually appealing clock app!
