Come on! How cute is the "Angry" key (aka caps lock) included with this decal modification designed for the Apple Wireless and 13" Macbook Keyboards? Same goes for the delete and space bar...in fact all of them will likely delight both kids and adults seeking a little personality per keystroke.
The $12 decal set offered by Etsy seller, Killer Duck Decals:
Our decals leave no residue and are easy to apply, printed on high quality vinyl and laminated with a heavy duty, slightly glossy, protective layer. Our skins are meant to make your stuff look cooler, not make them bomb proof. So don't go flashing them around in the bad part of town and skipping them across lakes because they do not grant your electronics super-powers.
