10 PRINT CHR$(205.5+RND(1)); : GOTO 10

As demonstrated by Casey Reas at the Eyeo Festival, June 2011, Minneapolis, Minnesota, a random maze generation program in one line of Commodore 64 Basic. The program uses the PETSCII character set, specifically the line character code of 205.5, plus a random occurrence of 1 or 0, which alternates between the / and \ characters, and then repeats without causing line breaks. This small program is shown running inside of the Vice emulator on Ubuntu. The recording was made with glc and compiz.
