What the fuck is wrong with people who develop sites like this. Just stop. Use HTML and CSS and stop trying to fuck around with basic things like scrolling. It's so fucking self important.
I thought it was a fantastic site. Got me interested, got me to scroll all the way and told me everything I needed to know in a very visual way. I really liked this page.
Same here on Windows/Chrome. Mousewheel scrolling jumps all over the place, grabbing the scrollbar does nothing, and all of the animations constantly restart after playing for a few frames.
