Haha, now that is different isn't it? For my regular visitors, this one is a good one for the theme of who's art is it anyway?
I can tell you it is the art of Phillipa Lawrence called Bound, Croft. It is a diseased Oak tree wrapped in cotton and I think last year it was red. However, after a year in the elements, it has turned a striking pink...especially against such a blue sky!
Other Skywatch images can be found here. Happy SWF :-)
It can be seen at Croft Castle as part of the Meadow Arts Commission 2009.
