OK. This is one of those things you say WOW when see it. My friend Boris, who is getting his masters in Electrical Engineering at Drexel, is celebrating his birthday today. His girlfriend Marcella made this cake for him and posted the picture of it on facebook. Those are programmable LEDs set to green blink :D. I thought it is so cool, that I decided to share (with permission, of course!). Happy birthday, Boris!!!
