Van Gogh Shrubbery....

I was in London recenlty and of course I took a wee visit to the National Gallery. At the moment there is an amazing representation on Van Gogh's Wheatfield with Cypresses outside, made from plants. I didn't realise what it was at first because I was so close but once I stood back I could see it. Its interesting becuase I imagine its going to change as the plants grow or die, creating a different image each time you go by. What a great idea!
