This animated cyberpunk/sci-fi story is a visual tour de force. Kenji is a teenage math prodigy recruited by his secret crush Natsuki for the ultimate summer job. But when Kenji solves a math riddle sent to his cell phone, he unwittingly breaches the security barricade protecting Oz, a globe-spanning virtual world. Like the Internet as conceived by pop artist Takashi Murakami, Oz is a pixel parade of cool avatar designs, kung fu jackrabbits, toothy bears and a bursting of colors.
