For NaNoGenMo 2015, my project was Virgil’s Commonplace Book, a computer-generated travel novel set in the Roman Empire. As always, the code is on Github.
There’s also a related Twitter bot, @erat_viator.
In both cases, one of the underlying motivations was to explore serendipity in publically accessible data. There’s a ton of databases of information from the Roman Empire, but sorting through the deluge of data is hard to do without context. The bot and the book add context as you explore the data.
