I guess it's pretty but the linked demo(?) page is quite confusing. The top article scrolls uncontrollably fast; at first I thought I had some input, thought I causing it to go up/down but couldn't figure out the UI. Why the bleep wouldn't it stop so I could read? Finally realized it must be a canned demo scrolling on its own, but a disorienting experience.
