Thanks! I found a funny hack: DVD logos generate stimulation per bounce, so ... let them fly for a few seconds, then resize window to small size and back. Lot of bounces as the logos get caught by the moving edge :).

Thanks, I spent my lunch hour completing it without cheating. Amazing!

Careful folks! This escalates quickly. Do not use xdotool on this.

Grateful it wasn't as long as Infinite Paperclips or Cookie Clicker, but still worth it. Great site!

Damn you! Half an hour later...
