I was trying to find an art history paper topic, but instead I found this. I clicked on this link because it said "virtual brownie" which (sadly?) is not what it sounds like. Project Virtual Brownie , from what I can gather from this movie, is trying to make virtual reality brownies--little gnomes, I think--move real objects. I'm pretty sure its magic.
I also learned about SUIs--straw-like user interfaces--which are machines that simulate the feeling of drinking from a straw, without actually drinking anything.
