I've been noticing that in the pictures. I keep remarking on how empty the lot looks and how small the building is, but then I realize there's supposed to be another building there...
It's probably being held up by issues with getting certain materials and contracts with whoever is going to operate the space. I know they want to bring back some semblance of the old fashioned belt driven system for the demonstrations, which probably requires a whole engineering firm to figure out. Depending on how fancy they want it to be I feel like it's one of those things that probably originates in Germany and gets shipped over here a year late. Seems to always be the case with specialty engineering. Hopefully it works out. I really wanted to see it make a come back the right way and I applauded them for their efforts to bring it back at least similar to the way it was.
