fixpixel is a simple terminal app for flexing the RGB subpixels in an LCD screen. The theory is that causing rapid on-offs can unstick a stuck pixel or subpixel. Of course in practice, this never actually works :). Still, it's fun to make terminal windows go into rainbow mode.
It uses ncurses to fill a terminal window with RGB colors at 60 frames per second.
ncurses and developer tools should be installed:
$ make
$ ./fixpixel
