This face is a cross between Simplicity and Segment Six, with a little help from Polar Clock by op12. I wanted a whole, filled circle to grow with the ticking seconds, but if I don't draw the second black circle (smaller so it makes the larger white circle look hollow) then the space underneath the circle has garbage in it. Not sure why, perhaps someone more clever than me can have a look.
BTW, I know the code is full of unused bits and pieces. I'll sort it out at some point, but all this has been a learning experience more than an attempt to create anything useful.
