Someone on Grand Designs had this in their garden. It was very impressive, but once he'd balanced them, he stuck a rod through them all so they didn't fall over.

I did wonder.

I wouldn't want to be too close on a windy day.

Pretty funky. Wouldn't be trying any arete probems on that.

Impressive balance skills. But gotta hope this won't inspire yet more hipster/gapyear rock balancing bollocks at crags, beauty spots, and in the mountains.
