So recently I saw a soda vending machine that scrolls thru like four types of soda offered. That's a problem for me. It was backlit and I know how two images can work by way of a VVVVVVV type of image but four? Only so much room inside a soda machine for lighting much less projection, and there was no points where the machine went dark, it just kind of faded one type of drink to another. How's Zit Done? This especially since it seems to scroll from image to image no matter what direction you see the machine at and the machine has the classic curved front? Believe it was like a 7-UP machine.
