Has anyone been on the foggy bridge yet?

I heard about this on Radio Bristol this morning, there's an artist from Japan who has attached fog making equipment to Pero's Bridge - the one with the horns. Every now and then the air fills with fog and you can hardly see anything, it's meant to be good fun and it is part of the In Between Time festival that has just started in Bristol.
There's a bit more about the Fog Bridge on the website, and I think I heard them say that the artist is 80 something. She is still travelling and exhibiting, which is always inspiring.

I'm hoping to go and see it this weekend.
I just hope they warn the cyclists that zip over the bridge that they are about to lose visibility!
