Any ideas?

A rather striking sight between the Mill bridge and St Paul's - does anyone know what it is and what its purpose is (I'm not being a philistine here - being interesting is fine in and of itself - i'm just curious)?

I realise this is a cliche, but how did we live before the web? It seems astonishing (and yet somehow we survived).
