Ideal for trade show exhibits or check-in stations, Sentina's new USign allows planners to create their own illuminated signage. The lightweight display frames are made of recycled plastic and are equipped with LED lighting. To create a custom display, simply print a sign on an 8½- by 11-inch transparency sheet and slide it into the frame. USigns cost $80 each and can be linked together to create a freestanding tower. The displays are powered by a 9-volt adapter, or for the tower configuration, there is one large adapter and a hub that can power as many as 12 panels at a time. The signs are available throughout the U.S. and Canada.
