I'm quite taken with the sculptures of British artist Anna Gillespie. She uses stone, bronze, acorn cups, tree bark and other materials to create striking images of human frailty. She explained why she makes heavy use of unusual natural materials:
Even speaking of 'nature' as something distinct from the human race suggests an artificial separation. We are all part of the natural world. Collecting beech nuts and acorns for sculptures, made me realise that every one is the same and yet different...just like us. Nature is so prolific.
