Possibly the most child-friendly work of modern art ever, John Deller's sculpture Sacrilege, began its tour of London in Hampstead Heath on Wednesday.
The 'sculpture' is in fact a giant, fully interactive bouncy castle, which kids are welcome to play on for free. It is also, for reasons best known to the artist, a lifesize replica of Stonehenge.
I am told by happy punters that it is indeed very bouncy, and hundreds of children (and a few adults) turned up on a grey morning in Hampstead to throw themselves around the famous pagan monument.
Queues can be long, but so is the bouncing time, making this unusual piece of artwork well worth the visit. It will be visiting several parks during the Games, as part of the London 2012 Festival.
It is open from 10am to 6pm each day.
