8 Bit Wood specializes in making video-game themed pixel art with thousands of little blocks of wood, stained and glued together and then sealed.
The website for 8 Bit Wood shows off amazing wall art inspired by Contra, Adventure, Ninja Gaiden, Excite Bike, Mario and more. But since there's no price listed (you have to contact the artist to get the break down), I suspect these bad boys aren't cheap.
