This guy is just out of control. After taking a brief break to work on his own independent film, Ben Heckendorn is back to his old hardware hacking ways, this time cramming a portable NES system into form factor barely larger than the cartridges it plays. Titled the "nPod," his new creation has a 3.5-inch screen, runs on four AA batteries, and is based on one of those "NES on a chip" joysticks. It's obviously about as small as a unit can be and still manage those beastly plastic game carts, but we're sure Ben will find another way to display his leet hacking skills before too long.
