Speaking of tiling shapes – this is the very neat-o faceted face of the new(ish) Conference Centre in Ottawa. It’s supposed to represent a tulip, somehow (I think maybe sideways, vaguely) but I think it looks more like a spaceship. 🙂

I’ve heard that triangular faceted buildings (like Fuller Spheres) tend to be really leaky in the rain because of all of the independently contracting and expanding surfaces, but I’ve been in the conference centre a few times and so far it seems pretty dry.
