Robert Swartwood coined a wonderful term called hint fiction, which is a story of 25 words or less that suggests a larger, more complex story. The definition was taken directly from his website: Robert Swartwood.
W.W. Norton will publish an anthology of hint fiction in the fall of 2010. Oh, and anyone can submit for a chance to be published in the anthology with some well-known authors. For more details, check out his site: Robert Swartwood.
And if you are accepted into the anthology, please let me know. :-)
