Fin-tastic

The Architecture of Funny Shapes was superseded some time ago by the New Boring.  But just when you thought that the straight line and the right angle had regained their rightful supremacy, it seems that vertical fins have gone all twisty...

...not just here in Farringdon Street, but on several big UK projects currently on the drawing board.   Did it start with the Olympic Stadium, which did something similar with its 'wrap' ribbons - or did they get the idea from somewhere else?

If you want to give your building's elevations a little bit more life than would accurately represent the suits that will occupy it, this is probably a better and cheaper way than twisting the whole building. .
