These vinyl Ghostly logo decals fit perfectly over the light-up Apple on the back of your MacBook, giving the little spookster a pair of eerie, glowing eyes. 

Scare the beejesus out of the other folks working at the coffee shop/airport/library/park with these 3" industrial-strength decals, which come in a set of two: one black and one reflective silver.

(If you're buying or have recently bought the laptop decals, be sure to check out one fan's how-to on getting the decal in perfect alignment on your Macbook Pro.)
