SMPTE v0.1 by Rob Lindman.  Here is the program description in his words:

i wrote this small basic program to approximate the display of smpte color bars, using reversed spaces only, and the complete palette of the 64. only superman can understand what I just said. "send one million dollars."

spacebar toggles a message which can easily be customized by editing string array.

if the message seems weird, it was inspired by the max headroom post.

anyway, feel free to mess with it, I just wanted to try to make a tiny little colorful screen. I would be interested if people choose to make it more interesting, compact, or have more screens.
