"Project Mathematics" from Caltech

"Project Mathematics" provides fantastic videotape and workbook modules
and explores and explains basic topics in high school mathematics using live
action, music, special effects, and imaginative computer animation.

Tom M. Apostol, Emiratus Professor of Mathematics at California Institute
of Technology (Caltech) is the main architect behind this very successful effort.

The tapes (also available in PAL format) are distributed on a nonprofit basis.
Currently production of the DVD versions is underway.
