Theo Jansen, has studied physics at Delft University of Technology, and since 1990 has dealt with the subject of kinetics. The 63 years old Dutch artist lives in Delft near the North Sea, and for the past twenty-one years, he has been constructing large-scale animas that can walk on the beach powered only by the wind. He calls them Strandbeests and they are made of plastic yellow tubes. Videos of those sculptures have been seen on youtube, by thousands of curious viewers and have also drawn great media attention.
