Ever wanted to do something to your DMG besides paint it? Me too, so I busted out my sculpting tools today and some Aves Apoxie Sculpt and went to town. My original idea was to just do some red Mario style bricks, but in tradition of the DMG’s nickname “Grey Brick” I decided to do just that.

This guy refers to his Gameboy as DMG and say:
“The original Gameboy is Model number DMG-01. It stands for Dot Matrix Gameboy. In the game community we simply refer to them as DMG’s as apposed to ‘Original Gameboy’ or ‘Classic Gameboy‘”
I’ve never seen it referred to as “DMG” I think this guy is making shit up.

I actually think that looks very cool, Now if only he/she had done the back aswell
