Lobby display screen for visitors

We have several huge and really cool projects going on at my office. The problem is that we aren't really showing them off, not to us who work here or the people visiting.

I want to create a prezi to be used on a big touchscreen in the lobby. With a "first page" of a kind where people can choose what project they want to look at. So basically a prezi where you have a couple of options at first, with each option having a presentation in itself.

Anyone have any good examples of similar prezis or creative ideas on how to do it?

Thanks!
