Pretty impressive.
In a former life, when I was still young and innocent, we used to hang out at this place quite a bit in summer.

Fortunately I never had any artistic talent apart from photography, so I left it at that. Somewhere in one of those storage boxes I must still have a few hundred over sized prints of what I considered world class pieces back then. I've forgotten all those IN names, but artists came from all over the world to that place, you might or might not recognise some, Clutch.
Love this video too once it gets going (apart from the wonky camera)
