Nice approach.

You could also do FFT displays with the simple LED device.

I would use a little speaker to also produce some noise. Nothing like hearing pulses arriving to make the lab a happy place.

Neat display - you're halfway to an oscilloscope there. (I'm glad I didn't put you off - there's room here for as many different logic probes as people want to do.)

One thought that occurs to me is that it should be possible to use whatever interrupt-on-change feature the Atmel processor has to detect short pulses (if anyone wanted to extend the functionality).

BTW If you want to enter the actual competition, strictly you need a video.
