I saw someone at school who had this neat cover on their MBA 13". It was super thin, black, look like it clipped on the sides (minimalistic-ally), looked like it was pretty grippy for how thin it was. I only saw it on the lid, so I am not sure about the bottom. You could still see the apple logo as well, when turned on...can anyone think of what this might be? ahaha Google is coming up short for me.
