Immersive Linear Algebra

I've benefited a great deal from the interactive exercises at Khan Academy, and I wish these folks the best. It's a huge undertaking to go beyond static illustrations, to animations, to user-interactive immersive elements — and to make it all work smoothly across many platforms and devices.

LOL, when I click on figure 2.3 I see "Firefox prevented this site from opening 21 pop-up windows." http://immersivemath.com/ila/ch02_vectors/ch02.html#fig_vec_...

Obviously a bug and not anything nefarious. Seeing this just makes me feel more grateful for their efforts.

This is an awesome idea!

The problem is that it only covers half of what you need to know in linear algebra. What about the Spectral Theorem? What about positive definite matrices?
