Looking for something to do with the thousand LEDs I bought from Electronic Goldmine, I decided to make a small pyramid. It reminds me of the Sol LeWitt sculpture, but on a much smaller scale. The LEDs are nearly cubes, so they stack nicely. The twenty-five LEDs in the pyramid are wired as a 5x5 matrix, and each LED can be controlled individually using a PIC16F648. I also extended Animator, my animation editor application, so it can be used to edit the animations.
