My hometown's planetarium uses this. It looks absolutely INCREDIBLE!Some shots of the final finish material from earlier today. The small sample looks great. This thing could be quite "sexy" when done.

The finish panels need only be attached on one side of an expansion joint leaving them free to move in expansion (heat) or contraction (cold) the result being that the expansion joint will not be visible in the finished product.I know it's still under construction but I hope those seams in the metal cladding will be blended in somehow because they look very obvious right now.
