Follow the upside down tetrahedron

I know it's wrong to say that it's upside, because who decides what side of a shape is up. I mean, how do you know if a sphere is upside down? Anyway, back to the photo. Again, did the usual with the only twist that I accompanied Nick to the Jack Kilby Computer Center. I needed a place to read, and he needed someone to bounce ideas off of.
When you see a large triangle or tetrahedron pointing down to one spot I get the urge to go there. Much like the urge I had as a kid to find the end of a rainbow, or follow an indicator in a computer game.
