Microsoft's research division is doing tours across university campuses and rather than turning them into snoozefests they're showing off an incredibly prototype. It's a clear glass display which accepts input through voice control, touchless gestures, pen and eye-tracking.
iStartedSomething has videos showing the prototype in action, and it looks like it's got quite some potential. I can't wait until displays like this are sold so that I can control everything with foolish hand-waving. [iStartedSomething via Slashgeat]
