Sycorax is a Twitter client, written in Python, that choreographs the online behavior of fictional characters. Other tweet schedulers make your personal Twitter stream look like a clockwork robot is behind it, posting tweets at the optimal time for penetration into your social network. Syxorax lets fictional characters use Twitter the way real people do. Your characters can post at odd hours and talk to each other, taking their lines from a simple script you write, but without any ongoing work from you.
