Andy Goldsworthy's work inspires me at the minute, since I saw the sheep wool on the stone wall... It reminded me so much of the white fluff that that blows from the trees here in Budapest, and lightly floats in every crack and open window. I've never seen this before, maybe it happens at other places too, but it It also clings to pavement edges and lands in puddles where it gets soaked and changes from light and fluffy to dirty and heavy.
