Chumby with composite video output

Someone managed to post a pretty neat method of coaxing composite video out of a Chumby. For those who are not in the know, the Chumby functions as an open source connectivity device which is able to undergo a decent amount of hacking to have it suit your needs and fancies. This modification is not rocket science though, as all you need to do is patch some pads on the motherboard while loading a custom kernel to support the external output. What other cool stuff can you think of when it comes to the Chumby?
