Cowculations: Gingerbread Man

Dr. Mu
Journal / Anthology

Year: 1998
Volume: January/February
Page range: 55-57

I recently read an article by Robert Devaney in an old issue of Algorithm, published in January 1992. One of the first curious objects he happened upon while experimenting with computer graphics was a gingerbread man. It started with a very simple iteration in the plane, beginning from a single point. By graphing the orbit of the iterations of this point, the image of a gingerbread man magically appeared. This I had to see. His gingerbread man function defined on points in the plane can be written in Mathematica as GMB[{x_,y_}] :={1-y+Abs[x], x}
