Thank you! I've wanted to create backup videos as a fallback for people who cannot get the demos to work, but I haven't been able to get recording working properly.
Well in case this helps at all, I've just created (not very optimized) animated GIFs of them all: http://no.gd/mariowater/
If you decide to use them, I'll leave them there as long as it causes no bandwidth issues, but you might want to mirror long-term :-) (and run them through an optimizer)
