This photo brings back some memories for me. This was shot in the Science Theatres lobby area at the University of Calgary where I spent 5 glorious years getting my undergraduate degree in Economics. The crazy looking metal sculpture in the centre of the frame is called ‘The Zipper’. Both screw-like pieces of the sculpture are able to rotate, plus the entire structure sits on a rotating mount allowing the sculpture to spin on two axes. It is considered good luck to spin The Zipper before writing an exam (unless you were an engineering student for some reason), so during midterms and finals this thing was almost always in motion.
Good luck to all those students returning to the U of C this fall!
