invaders [1] invade your terminal with colors or strips. It has a few command-line options, but the `-c` color modes is that you want mostly. It has four modes: row (default), seg, all, and sys (0:02).
As you can see me running the first three in Bash `for` loop (0:03), because it didn't work with `watch -c`, can only get me monochrome color.
Frankly, I do not know the usefulness of this script except to bulk up your terminal screenshot when showing off. Screensaver perhaps?
