Aleks sends in this link to an interactive statistics web course and writes, “It requires registration, but I highly recommend you go through this. You will probably not like the statistics teaching style that goes back to Fisher’s 1930s textbook, but it’s hard not to appreciate the effort that went into interactive 3D demonstrations of various concepts.”

There is something incredibly old-fashioned about what they’re teaching, but I agree that the 3-D graphics are extremely impressive. Probably the wave of the future, once it can be combined with a more up-to-date (that is, ARM-style) set of statistical concepts and methods.
