- This works, of course, but you'd be surprised what a plain .plan file
- (without program) can do. You can fill it with all kinds of terminal
- control characters, no-op sequences for timing, etc, and get some
- remarkable graphic effects without any executable code (other than
- finger itself). When I was in college, someone I knew had a .plan that
- used vt-100 graphics to cause a PacMan to run across the screen, eating
- characters. (Mark V., are you out there?)
