   a overhead projector puts images on a white background. for example you could produced 10 pages of notes, that you need for 3 clases. Instead of re-writing it 10 times, just write it once on a piece of overhead plastic, and then project it onto the board. Then reuse it for your next class.

   It is an optical device that projects images or wrinten matter “over the heads” of an audience onto a reflectant screen

   It uses clear acetate to hold the images or drawins; this acetates can be done by hand or by a computer, and used over and over again.
