Based on the way FIRST has treated the hint in the past, this image seems pretty different. My conscience still tells me that the 5 has something either to do with sports or entertainment.

There must be a variety of levels, or platforms, and like Johnny 5, there will be some mini-projectile involved. I was told by my teacher that something related to basketball may even be put in for this. Tubes may connect these platforms, and contain some substance which revolves around the field in those tubes, activating some switch in the current platforms it goes through.
