I've spent the last hour destroying web pages using this Asteroids bookmarklet: Facebook, Twitter, Scoreland (NSFW), Justin Bieber's site... Everything can be destroyed exactly like in the Asteroids game. Watch this reader lasering Gizmodo down to smithereens.

Created by Erik Andersson, the javascript bookmarklet will work with any page, identifying objects and using the spaceships cannon to reduce them into a shower of sparks. I wish the objects themselves broke into pieces—like in the Asteroids game—but that doesn't make this thing any less enjoyable. [Github via John HerrmanVideo courtesy of Giz reader Joel Farris]
