A toy fan was connected to a PIC microcontroller, which controlled the flicker of the LED candles! Blowing on the fan triggered a mechanical switch, which was counted by the microcontroller and turned off the LEDs. If you didn't blow long enough, the candles would turn back on like those trick candles that keep re-lighting!
Pretty sweet (Literally). My buddy Erik is going to put an Instructable on this soon, i'll link to the post when it goes up!
