Brutalist beauty?

Simple shapes in close proximity. I like their massive forms. In contrast there are some delicate wisps on the one one the left towards the bottom of the picture that I find bizarre and fascinating. Any idea what they are?

Thanks for the compliment, they are actually bits of wire put on the building to try and stop pigeons roosting there and leaving their calling cards!

 

They haven't been overly effective, lol

Well seen and post processed, good work.

Thanks George!
