Not every extension in your Google Chrome install has to make you more productive, safer, or facilitate using your favorite websites. Suppose you want a way to unwind always at your fingertips? Say, like an air hockey game in your browser actions area?

Yes, this is pretty much just a a Flash embed in an iFrame, but it's still enjoyable. As a bonus, Air Hockey keeps tabs on your best score so you can feverishly flaunt your repeated dominance -- or remind you how badly you suck at the game.

Nothing like the feeling of emasculating yourself against a computerized opponent by scoring an own goal....
