Willard Wigan's artwork is so tiny a microscope is needed to view it. The Birmingham, England, native is known as the creator of the world's smallest sculptures. He makes small worlds of their own that are almost invisible to the naked eye -- such as a $300,000 sculpture that sits on a pinhead. Under a microscope, you see an elephant carved from a fragment of a single grain of sand. The tail is made from a floating particle of dust out of the air that you see floating," Wigan explained. How does he do it? Wigan uses tiny, homemade tools to carve his sculptures out of grains of rice or sugar, and paints them with a hair plucked from a housefly's back. He said he's able to slow his heart down to work between the beats to avoid hand tremors. "Underneath a microscope, those tremors become an earthquake," he said. According to Wigan, his obsession with tiny objects began when he was a lonely 5-year-old. "I have learning difficulties. You know, I can't read or write. But I had to find a way of expressing myself. The teachers at school made me feel small, so they made me feel like nothing. So I had to show them something." He started by making houses for ants as a child, and now he creates entire, tiny worlds. Wigan has something to prove, which makes the misery worthwhile. "I'm trying to prove to the world that nothing doesn't exist. It doesn't matter how big a building is, it's made up of molecules. We ignore the world that we can't see."
