Best buy has a cool new gift card that contains a built in programmable scrolling LED display. Its the size of a standard gift card but a little bit thicker. The display is about 7 characters wide and can hold up to 6 unique message of 256 characters each. The scroll speed and LED intensity can also be adjusted. It uses a single 3 volt flat button type battery that is easily replaced. There are probably a million different things you could do with them in a theater room. I couple ideas i had off the top og my head: price display in candy counter, cooming soon or now playing message on poster frame, watch your step message on your riser, welcome the the XXX theater signage near your door, etc. I'm sure the creative folks on this forum will think of many other novel uses. So if you were planning on buying anything at best buy stop at the customer service desk first, pick up a few of these gift cards and put a few dollars on each then just use them to buy whatever you were gonna buy with them then keep the cards.
