CSS is DOOMed!

Try it out! But... not every browser can handle it. This is taking the browser to its limit. Chrome has some issues. Safari too. Bugs will be filed.

@html5test Nice, too bad the mouse doesn't work...
@ZoidbergForPresident It should work when you go to Full screen mode (left square button in the top right), which uses Pointer Lock to capture the mouse if supported by the browser.
