Like any artist, Shelley does best when primed with some inspiration. The developers write that Shelley “takes a bit of inspiration in the form of a random seed, or a short snippet of text, and starts creating stories emanating from her creepy creative mind.” Horror-loving denizens of the internet can help her churn out nightmarish stories by submitting their own sentences to compositions in the making on Twitter. Like a digital game of exquisite corpse, Shelley will take those sentences forward to create a complete story (and in the process, take “exquisite corpse” to a more macabre level).
