Daniel Paul Tammet
Tammet is a person capable of converting numbers into images and carrying out those so called difficult mathematical calculations instantly without any glitch. For instance, he claims that 289 is an ugly image while 333 is attractive and pi is a beautiful image. He is also capable of sensing whether a number is prime or composite at once while we, on the other hand, take minutes to take a decision. Not only this, Tammet is able to create drawing, most probably watercolor like his painting of pi.
