My aunt used to work there and my grandparents lived right around the corner. I really enjoy looking at your photos since I am from Cleveland originally.
F. Buckminster Fuller would be proud, and I'm sure he used pi in inventing these structures! This image seems a bit blury, perhaps a motion blur? I do like how it communicates pi by showing us lots of geometry.
An awesome picture, and building, I think the shot could have been a little wider, so you could see the other legs, but I like how the trees are cropped right before the line in the dome.
