This guy decided to turn himself into a Game Boy. He used a bunch of cardboard and a laptop is hidden inside that controls the screen. As you might expect and as he states himself, it’s a pretty fragile setup, but well worth it.
It even has the sound effects. The sad thing is that while in the Game Boy suit he can’t play himself. He can only watch others enjoy a game of Tetris. Pretty cool costume. You have to love Game Boy a whole lot to turn yourself into a walking handheld.
I’m assuming the buttons all work and that that kid playing just really sucks at Tetris.
