Procedural generation is not just for games. There’s a whole world out there to explore, and I don’t mean a terrain generator. One application is Twitter Bots: software that automatically posts content to twitter.
Some, like @everyword or @IAM_SHAKESPEARE are simple recontextualizers, linearly reposting a corpus. There’s some clever results out there, but it’s fairly easy to grasp how they work under the hood. The interest comes from the bite-sized juxtaposition, not the mechanics of the shuffling.
Others are more ambitious, using everything from Markov chains to syntactic analysis to image manipulation to procedurally generate brand-new content automatically. Some just generate one type of thing repeatedly, while others take advantage of their platform and react to other people’s tweets or start conversations.
