A collection of visual wordgames and puzzles that will amaze and delight.
Burkard Polster is a well known juggler, magician, origami expert, shoelace charmer, ambigram artist and 'Count von Count' impersonator. As a pure maths lecturer at Monash University, he also spends a lot of time turning students into maths demons and having fun doing serious research.
Eye Twisters is all about ambigrams - words that are written or drawn so that they can be read in more than one way, back to front, upside down, turned this way and that. If you enjoy Escher's drawings, ambiguous figures, puzzles, optical illusions or mathematical recreations, you will love ambigrams.
Here, over 200 of the best examples by the world's top ambigram artists are showcased, many for the first time. The history and philosophy of the form are explained, you can learn how to make your own ambigrams and sharpen your mind on mind-bending problems (topsy-turvy Sudoku, anyone?). The result is a wholly original, magical book that all age groups will find irresistible.
'Imagine a world in which the spaces between things are also things - as if there are no spaces. A world in which things turned upside-down are still right-side-up. A world in which the laws of nature as we know them can be suspended or ignored - or perhaps extanded - at least for the time being.' John Langdon, foreword.
