My guilty pleasure is video games.  I love figuring things out.  And I'm extremely patient.  Ubisoft's game "Tom Clancy's Splinter Cell" is a first person game requiring a lot of patience as you sneak around trying to avoid being detected by the guards.  This level takes place on a cargo ship.  To plan my strategy and keep from getting disoriented in the secret passageways at the beginning of the level I mapped the space.  Drawing this map was as much fun as playing the game!
