I tried it on firefox and it looks really good for the first few seconds (It gets rendered properly) and then all of the buttons scatter accross the screen. I'll have to try it on a mobile, but from what I saw it looked awesome!
yeah, all that you are seeing is a screenshot of it so that people have something to look at while it renders the interface and loads. If you check the error console you will see a critical error with the JavaScript that stops it from loading. Chrome seems to work best right now for desktops, and it is know to work on iDevices with less bugs then Android (see the known issues on the Home tab).
I've added what is called application caching, so now when you visit it you will only load the application stuff the first time (not the music though). This will save a tiny bit of bandwidth. You can also load the page if you arenot connected to the internet, it will just error out though :p
