Hello,

A simple LED Message Flag like this one:

With minor surgery can be seen by video cameras and not the human
eye. Did you ever want to give your boss the bird, or tell him/her to
*** off after having been fired?

Replace all of the Red LEDs with Infrared LEDs and only video cameras
can get the picture. You could stand looking at your boss right in
the eye, and until he/she gets to the video tape, won't know you quit.
