Really impressive work! I agree with what most people said before.
For me, the 3d surface plot doesn't work and neither does viewmat (both on android/firefox and on windows 10, chrome). I don't know whether it's still work in progress, but it might put off people if some of the examples don't work. I'd be happy to help debugging it, if needed.
