R ydell had liked doing Dream Walls, when he was a kid in high school. It was this Japanese franchise operation they set up in different kinds of spaces, mostly in older malls; some were in places that had been movie theaters, some were in old department stores. He’d gone to one once that they’d put into an old bowling alley; made it real long and narrow and the stuff sort of distorted on you if you tried to move it too fast.
