this is webgl (at least the mathematical visualizations)

For some reason the Mandelbrot fractal (slides 30 and 31 in the second part) didn't render in Firefox but they worked in Chrome. Everything else seemed to work fine.

Thanks for pointing that out! I just accepted the black panes in stride because the caption said "...this is not so easy to visualize"

I also noticed that the text of the page was angled away on page load in Chrome, but not in FF

Oddly enough, it works fine if you open the iframe in a new tab. I think it may just be Firefox denying my admittedly greedy requests for video memory.
