A tiny, intense genre is constrained writing. You’re doing it already, writing under the constraint of 1,024 characters. Another interesting constraint is avoidance of a very common letter, as in the French novel “A Void.” It’s 50,000 words long, none of which contains the letter “E”. Read about it here, http://en.wikipedia.org/wiki/A_Void

Write a story that does not contain the letter “A”.
