Thought Bubbles

I want to make some very small, very low power, sculptural computers. They only need to be able to access wifi networks and browse websites (I'm thinking Wikimedia Commons and Google image search). They very nearly qualify as wearable computers. They're shaped like thought bubbles and are worn sticking up from some kind of hat or other person to computer interface. The idea is that the wearer would be able to grab an image from the internet and display it on their thought bubble screen. It would give the adorable illusion of being in a comic book, and it would give others a little insight into the thoughts of the wearer. Neat.
