I have written in Squeak an interpreter for a programming language called SC5, based on the video game Space Channel 5. Space Channel 5 is a fun game with retro Peter Max style visuals, and itfollows a space reporter named Ulala as she tries to beat aliens byrepeating their dance moves, "Simon Says" style. The dance commands are"up", "down", "left", "right" and "chu" (each corresponding to a buttonon your controller) but the sequel added the "hey" command also. Because everything in the futuristic world of Space Channel 5 runs onfunky dance energy, computers must be able to accept dance commands.Hence, the only commands available in the SC5 language are the dancingcommands from the game: "up", "down", "left", "right", "chu", and "hey".
