Output?

I was casually talking to Craig about this project today and he suggested an interesting output for my group's project involving a fan and some miniature balloons. When the user is interacting with the input, the mother robot is sucking up the balloons in the scene, which then triggers the output involving a fan which blows out miniature balloons into the physical world. I thought this idea was pretty clever so I pitched it to my group and they seem pretty keen on working with this idea. We might work on this extra detail if we have the time.
