He made a bunch of arcade games out of cardboard in the front of his dads car parts store in East LA.
HERE is a link to the youtube video that tells his story.
I remember making a wall of cardboard in my room when I was a kid. My sister and I shared a room and we wanted our own rooms so we erected a homemade cardboard wall, complete with door and a window that closed. I think we taped it in place--thank you Mom and Dad--to the ceiling and floor. I don't remember how long we kept it up, but I always draw on this memory when my own girls have wanted to do some crazy, messy project.
