Being an artist uses a download to be hard. We had to collect all your nail clippings for twenty years and then make them into a mosaic of Gorbachev raping an owl, or had to develop a process to preserve plastinization human tissue, convince the Chinese government to give them the bodies of prisoners , and then carefully bend and shape their bodies into strange positions. If you feel lazy, giraffe dung used and age of the baby teeth to make a portrait of Mother Teresa, but even that took some effort. (It was not the car park, to convince the guards that were not totally crazy, hauling buckets of shit round giraffe, etc.)
