This very cheap variant of the PRO screen has only 4 frames, suitable for having a screen and doing random things ... Not really useful, it's like a demo. And it IS a demo for multiple framed animations. Instructions ingame.
Just to say this is unfinished, there is no complete instructions right now. This serves to animate a 4 pixel screen for 4 frames . Future plans for this is a 5x5 screen with 100 frames
