Gnarcade is a a rap music video that mixes up 8-bit video game foes with competitive skateboarders and snowboarders. It was created by Knifeshow Inc, and features music from Ground Up. Skateboarding and snowboarding from Scott Stevens, Micah Hollinger, Chris Beresford, Tim Eddy, Ben Bogart, and Casey Wristsman. Besides all the gnarly extreme sports dudes (Oi! just thinking of all that physical activity makes me breath hard) there are a enough animations of characters from old school video games to keep nerds happy. Space Invaders, Bubble Bobble, Pac-Man, Frogger and — wait for it — Portal.
