My favourite five for this week are :-
Jeff Han's Multi touch interace : because it is breathtaking.
YouOS : because building an entire OS in Javascript is an insanely correct thing to do. The worst thing about Javascript is the name.
Nada just because it points the way to a future where the physical / digital are designed in parallel
What's up : because it is such a simple and useful interface
E-Machine Shop : not because it's new but just because it's wonderful
