Mosaic bench

Wouldn't want to sit on this bench if I had my nicest clothes on - looked a bit sharp in places! Another example of graffiti/arty/mischievous activity in Hyde park. Today's weather was nice - odd spots of rain but the park looked nicer today than it did yesterday!
I hope I keep stumbling across things like this - I don't think i've noticed it before as I take another route through the park on my way to lectures - or,more commonly, into town for shopping/drinking etc
