Andy Goldsworthy is a sculptor who creates art in and with nature. He is one of my favorite artists. This sculpture was made by laying leaves from a Rowan tree around a hole. He also makes sculpture by freezing icicles together with spit, rocks and trees, it's all very interesting to me. To learn more about him google his name; there is lots of information about him out there or click here. The below sculpture is what inspired my "O".
