Inspired by the large backlit panels outside old-time cinemas and theaters that would tell people what was playing at the venue, the My Cinema Lightbox is a cute tabletop accessory that can be used to display any message you like. Each lightbox comes with the box itself, and a series of alphabets + letters printed on transparent sheet plastic that you can fit onto the lightbox. Each lightbox offers an option of either running on 6 AA batteries or via USB.
