What Was the ‘Random Gymnastics’ Going on Downtown?

So there I am doing my show (ahem commercial free every weekday at 4:20 p.m. every workday until 5:56 p.m.) when fellow radio guy and production person Bobby O storms in the studio and says, "Yo, I know you like random stuff that happens in Lafayette Square...look out your window."  So I look outside our studio window that indeed looks over Lafayette Square in beautiful downtown Buffalo when I see some randomness...

....any idea what was going on?  Photo shoot?  Video?  Figured I'd get some answers from the public since they were gone before I could take the elevator down to catch up with them.  Thanks for reading today's randomness!
