I did a little research project into interactive drawings a while ago. The above diagram basically sums up my findings.
The first type of interactive drawing - an image containing a set of rules - could be, for example, a 'Where's Wally?' image or a maze.
The second type of interactive drawing - a set of rules containing an image - could be, for example, a dot-to-dot puzzle or one of those grid-based, Japanese logic puzzles containing an image.
