His work is beAutiful, isn't it. Look up his midsummer snowballs work, he. Made massive snowballs up in Scotland where he lives, and trapped different things in each as he made them like sandstone crumbs and fir needles, took them down to london and put them on the streets where they slowly melted and left piles of debris. I have his book about it, it's like a photographic diary of the snowballs. Beautiful.
