Simple MacBook Pro icons in 512, 64 and 32 px sizes.
I am not sure if I am finished with these yet, since there are a few details missing. So if you use them, do check back soon as there might be some updates.
Credit to Apple for the Snow Leopard wallpaper. Rest of the stuff is all done by myself.
Fixed the corrupted image problem, added a 128px icon.
[EDIT] updated the ICNS file with one done properly by the generous larzon83 [link]
