"Hen-na Rittai" by SUGIHARA Koukichi

SUGIHARA Koukichi is a expert of mathematical engineering, computational geometry, and computer graphics. When he tried to let a computer recognize a solid from a picture, he noticed that some trick pictures can be realized! For example Escher's "Ascending and Descending" and "Belvedere" - these can be made in real! This book (the title means 'Strange Solids') contains unfolded figures of such solids, so we can easily make them! I am going to make them in near future! ^^
