After viewing that video I knew I had to have it, I I went on a wild goose chase, looking at forum posts stating it is impossible to download the program, because it was a "Strictly MIT professor " piece of software. upon further digging, I found it :D. I downloaded it from http://www.microsoft.com/downloads/details.aspx?FamilyID=56347faf-a639-4f3b-9b87-1487fd4b5a53&displaylang=en.
and upon instalation, discovered, it was for tablet PC's ONLY! so I dug and i dug, and I dug some more, and found it's source code, posted on microsoft's website! ( found here http://research.microsoft.com/research/downloads/Details/aeee3085-a219-47d6-88fc-a2501f00800d/Details.aspx)
I was able to compile it using Visual C# 2005 Express Edition, add a few things, and it now runs on any PC! So in this instructable, I will show you in detail, how to download the source, convert, compile, and run the program.
