Keeping the thread off topic...
I have been trying to find a photo of the infamous staircase to nowhere at the Pitt Student Union. When I think of it, its shape IS an Omega - a horseshoe shape, flaring at the bottom. The SU was actually the Hotel Schenley at one time, "the" posh hotel in Pittsburgh, and the staircase went to an exclusive ballroom on the mezzanine. Of course, that's before the geniuses at Pitt decided to kill the whole concept - so now it's just used for photos. And yes, you do have to walk up & down with great care & grace.
Anyone have a picture to back me up?
ETA: found the following. Mods, if you can scale it down, please do so. There are no copyrights on it (and usually not that much furniture!)
