Ask HN: Cool Arduino projects

[nbenita]

I'm looking to get into Arduino (or We-IO) and in need of inspiration.

What are some cool, small, DIY projects you saw, or wish to see utilizing the Arduino micro controller.

Thanks!

Everyone out there seem to start out with a CI traffic light using Arduino. This is no exception :).
