Art-in-the-sky

My youngest daughter and I had a quick day-trip to Glasgow today to do some things, and following the advice of a fellow-blipper, who encouraged me to "look upwards when you are in the city" I caught this image. It is part of a huge metal sculpture on the facade of the Princes Galleries on Buchanan Street. I'm not sure what exactly it is supposed to be, but it looks impressive!
