I have multiple sets of story cubes. My favorite way to roll out of a slump (smile) is to randomly pick one from the action dice collection and four from the others all mixed. You may end up writing a story with an alien and a princess which can be fascinating.
In FAWM I rolled a grouping each week and let folk grab what moved them. I'm also willing to roll one specifically for you if you want your own energy in the roll. If you really want your own energy, roll your own - either physical or virtual - dice.
Whichever way you roll, tag it StoryCube so we can find each other and post the link below.
