British author, actor, playwright and polymath Stephen Fry picked a particularly interesting serial number for his personal Gömböc: 1729 is not only the smallest integer which can be constructed as the sum of cubes of two integers in more than one way, this property was pointed out by the mathemtical genius Srinivasa Ramanujan to G.H. Hardy when the latter visited him while Ramanujan was ill. Stephen is proud of his special Gömböc, he even tweeted a special message on the subject.
