This is the clock build by Gary. He used automatic color-changing mood LED's.

A very unique clock, with all these LED's changing their color more or less randomly. Thanks for the pictures, Gary!

Gary: "I was surprised how easy it was to build, even the surface-mount transistors weren't as difficult as I was expecting, even with my less than perfect eyesight. As you suggested, I used a pair of cheap 2.75 reading glasses, which worked really well".
