Spraycan - vandalise your page
This is what Mitya does when he's bored. This allows you - or rather your site visitors - to take a break from reading your blurb and graffiti your page like it was a wall.
Once the ap starts, you paint by clicking and dragging on the screen. A toolbox allows you to pick the brush colour and size.

The only problem is that clicking and dragging always means selecting text. To my mind there's no way around this apart from in IE (which defines a special text select event, whereas in other browsers you can only return false from the onmouseodwn event - not really an option for a script that listens for mousedown to know when to start painting).
One possible fix would be to append brush strokes to a new, invisible canvass rather than to the itself. Then, during painting, calling event.stopPropagation() would ensure the drag action never made it as far as the body's text elements.
