LEGO + OASIS from Intel
This reminds me of some of the work I've seen at emerging-tech think tanks like the MIT Media Lab (Tangible Media comes to mind), only this uses LEGO. As someone who played incessantly with LEGO toys and blocks growing up, this is right up my alley. Seems to be a great example of digital and physical elements coalescing to create a more magical playtime experience. I know for a fact my 3 year old twins would go bananas for this type of thing.
