I came across this YouTube video a couple of weeks ago. After seeing it I wanted to know if this was real software or something that was being developed internally somewhere. It turned out Microsoft and MIT co-developed the software called “Physics Illustrator” which is demonstrated in the video.

 

The software is built for the TabletPC, and is freely available for download. If you have a TabletPC get the Physics Illustrator from Microsoft’s web site and try it out.

 

The source code is also available from Microsoft Research here.
