Kick Ass (Game) — Turn any site into a Space Shooter. Destroy the Web!

Use this on Emojis Earth & Porn. Enjoy. :)

This is a pretty fun idea. Drag a bookmarklet into your browser. Clicking the button inserts a tiny spaceship into the website that you control with [SPACE] and the Arrow keys.

MailChimp had an Easter egg, where if you searched for "boredom," the screen would turn into an asteroids game, like this. Not sure if it's still around.

Muahaha

That's awesome :D So much fun!
