Really clunky, jittery scroll with a load of blank space for me. Would much rather a clean, simple HTML+CSS layout without all the fancy javascript. (IE 10)
Indeed, first time I come across such a website where scrolling is not jittery as f and either too slow or too fast! I generally hate these kinds of website, but this one seems executed flawlessly.
...or maybe kudos to the Chrome/Webkit team for finally fixing their weird scrolling behavior :) Years ago when I tried to implement such a thing myself the only browser that provided a decent experience on all platforms and devices with respect to such a scrolling-driven site was Firefox (and yeah, Safari, as Apple had a page like that themselves showing some mac pro or smth... but that worked like shit on anything except Safari on MacOS).
