Title: Pickover's puzzling nature strikes again
Review: Clifford Pickover truly seems to be a Renissance man. His previous forays into conundrums and puzzles have ranged from time travel to hyperspace to infinity.This time, its cryptography. While some of the aspects of these puzzles might be hard for some novices, and I could wish for room and space to more easily work on the puzzles, the puzzles themselves are a joy to play with.If you like cryptographic analysis, enjoyed Neal Stephenson's Cryptonomicon, or want to try a brain teaser of a different sort, then you might want to delve into Cryptorunes.
