Wall of calculus, from Blinkx
By Murray Bourne, 06 Mar 2007
This is quite something.
Blinkx searches through the audio track of videos to give you a more relevant result. (A Google search is based on the title of the video and maybe some tags that people have added to it, but not the audio.)
You can get a "wall" of videos on whatever topic you are interested in.
Go see a wall of calculus. Enjoy.
