every Arduino accessory has to be useful. Heck, some of them don't have to do anything at all except, perhaps, make you smile. And that's all the Googly Eye Arduino Shield promises to provide -- a little cheer and personality to add to your latest hack or project. The $7 shield is simply a platform with stacking headers, so you put another shield on top if you like, that sports a pair of googly eyes. Best of all, it's completely customizable. The kit comes with two pairs of different sized peepers which you can place wherever you want. Add all four if you like! The blank white slate leaves you plenty of room to doodle, add a smile, eyelashes or, if you simply must ruin it by adding functionality, a mini breadboard. You can see the Evil Mad Scientist-made shield in action after the break but, honestly, if you're not sold yet you never will be (also, you probably don't have a soul).
