With three of the pentomino letters you can make FUN. With all twelve pentominoes you can make a lot more fun. This exceptional book abounds with fanciful congruences, enclosures, tilings and a host of combinatorial squares: ConMagic, EyeMagic, GeoMagic and SymMagic. Many of the results are far from trivial, obtained by extensive research and programming. Their complete uselessness and beauty compete fiercely with each other. Almost every page bears witness to that by colourful figures. You are warmly invited to marvel at them. Have FUN!
