Dutch artist Bert Simons has discovered a way to create very life like 3-D sculptures out of paper. He first maps his subjects' faces using sophisticated tracking technology and feeds the data into a computer. Then using some special software he constructs the subject’s contour and then print their form on paper before putting it together using glue.
