Sour's 'Mirror' browser-based music video is absolutely wild

Is Japanese band Sour's "Mirror" music video the single best thing we've ever seen in a browser? It probably is. Load it up in Safari or Chrome and make sure you connect your Facebook, Twitter, and webcam -- we tried it out and it's totally fine. In fact, it's more than fine. It's stunning. Why can't HTML5 and Flash always play this nicely together?
