information system that runs off Wiis
amazingly, the information system is a Wii channel, and every one of these navigation TVs spread throughout the building has its own Wii attached to display the channel! the administrative backend can be accessed by staff via a web browser for easy updates from anywhere.
the other thing I forgot to mention is that each color corresponds with an area in the library (new books, children's services, multimedia, etc.), and that color is what appears at the top of the list when you're in that section. it's really amazing.
