Accidental Rosette, Partick Station

Here's an aleatoric* rosette I found, a result of the heavy duty refurbishing work now drawing to a close at Partick Train Station, in the West End of Glasgow. Somebody has used sticky yellow-and-black tape to attach non-sticky red-and-white tape to the outside of a window. I presume that the tape stretched across the gantry outside. No longer necessary, the tape was torn down, leaving the rosette.

*I'm such a show off: it means "random" or "accidental".
