Rory’s Story Cubes, a set on Flickr.
This is a game called "Rory’s Story Cubes", which are basically six-sided dice with pictures on them to inspire story ideas. We got two sets of 9 dice with 54 images; the blue set is a newer addition called "Actions", as the pictures suggest actions.
There are suggested rules, but no hard and fast ruleset that is demanded. Creativity is the goal, so players are encouraged to make rules for rolling the dice/cubes and generating stories as they see fit.
