It won’t be long before you can do things like draw the telephone of your dreams and have it work, and I was schooled on the concept of going from hand drawn design to working model with a minimum of cleanup (and apparently it’s still going on).

It’s one thing to hang out in 3D and play with toy physics, but the 2D Crayon Physics Deluxe is the coolest thing I’ve seen all week.

(I’m sure this one has already been dugg, but I just saw it thanks to David Sibbet.)
