Science Fiction Nerds Rejoice!

Artist and historian Ward Shelley was actually brave enough to attempt this:  a complete history of science fiction etched out in a colorful flow chart.  It spans over 2,500 years and includes such monumental movements as The Enlightenment, the birth of the Gothic novel and the rise of the popular sci-fi cult film, Star Wars.   Kudos to him for the commitment to this thing.  It's a beautiful, little monster.
