Jerry Gretzinger describes himself as an accidental artist. Faced with a boring summer job, he began to doodle a map of an imagined place. To develop it further, he adapted a pack of playing cards as a random number generator – and later to give instructions, as he developed the map, square by square. With a gap out for 20 years for raising a family, the whole project has been on the go for 50 years. Along the way, the development of computer/info technology has also changed its development. Intriguing story. Jerry comes across as a gentle soul, whose mapmaking has given him and its visitors a great deal of enjoyment.
