Projectors? Mechanics! Video displays?

I just watched some videos about the print dress that was showcased at the 2012 CES show. It projected tweets onto a paper skirt. Is there a small, Arduino compatible projector out there? I saw one being used on the sixth sense TED. Video ( not Arduino, I think). I'd love to use on in an up,coming costume project.

I have several other basic questions about mechanical devices, too.

Sorry you need to tell more to get meaningful help. e.g. links to a video to get started…
