The other day I bought a bag of one thousand green LEDs from Electronic Goldmine. The bag was sitting on my desk and every once in a while I would grab some of the LEDs and wonder what to do with them. I was arranging them in a perf board (from Radio Shack), when I thought it would be nice to arrange them in a diamond. This would highlight what I thought was the most interesting aspect of these LEDs, that view looking at the corner. The problem, for me, was that I did not feel adding a wire to each LED so I could plug each LED into a breadboard.
