Yes, but is it art?
I went to see Song Dong's biscuit-built Edible city at Selfridges yesterday - sadly one day too early: it is going to be dismantled and eaten today.
From certain angles, it just looked from random piles of biscuits. Every now and then though, you felt like you had died and gone to cookie heaven.
People of all ages gazing at biscuits and smiling - not something you see every day in London.
