If you play many games, then chances are good that you have at one point experienced a form of what’s known as the Tetris Effect. I know that I’ve spent many nights in bed sorting block formations behind closed eyes. Certainly this isn’t limited to Tetris though. The example shown here is of course Minecraft but this phenomenon is known to occur with many other┬ástimuli such as Bejeweled, Chess, or even weeding.

Hey, speaking of which, if you are like me and have never heard of Burrito Bison┬ábefore you should follow that link and lose a few hours that would have been otherwise productive. If you really have nothing better to do you might even consider looking up it’s sequel.
