Check out this interactive Turing Machine: Smiley

Some of the lessons/code samples have videos, like this Hilbert Curve one. 

@JohnAskew Where do we rally?  The internet? Wink  I don't know, but Khan Academy has a good reputation and excellent funding (i.e. Bill Gates).  I hope MSDN and C9 take a look at these ideas.

@MasterPie Also cool, and targeting additional needs; I can imagine the best of both worlds combining in the future.
