Catching up on Digg

When Digg first came along I found all kinds of cool things. But then Digg got too big, and one couldn't keep up with the stream of Digg posts via RSS. So I unsubscribed. Last night I decided to "catch up" by going through the Digg top posts for the year. This revealed a couple of gems. One of which is this demonstration of a physics modeling tool that combines gesture drawing, on-line whiteboard tools and the modeling software itself. Personally I could have hours of fun with this system and my kids creating our own toys..
