a POV display is normally a display that is moved fast through the air. the lights on the display will have a distinct tail on them so the graphics will look like it is floating in mid-air.
Instead I want to make an inversed version of the POV display. A similar version can be seen here: http://www.rotorbrain.com/blog/2009/05/ghostmatrix.html
To take the concept a little further I want to make the display hand-held and make it print on a surface coated with glow-in-the-dark paint.
