Ambiguous Roof illusion

This is based on: http://home.mims.meiji.ac.jp/~sugihara/ambiguousc/handout.pdf and is modified to be printable. Please scale this up to 200%. The illusion is better visible when you look at it with one Eye closed or make a photo with a cmaera. When you shade the edges with a plack pencil,the effext becomes much stonger.
