Is there supposed to be a player control or something in the middle of the screen? (It's blank.)

Safar 5.1.7 / OS X 10.7.4

Edit: Weird results redrawing the graphics when resizing the window with Chrome 21.0.1180.89 on Mac OS X.

Thanks for pointing it out, I have only tested it for Chrome. Will surely look its working on other browsers.
