Mix FiftyThree developed an app called Paper that made drawing on the iPad into a complete joy, now with the added feature of Mix, enabling collaboration with others remotely. The new feature allows users to riff on one another's sketches in a richly constructed, annotated system that ensures proper credit is given. This system feels like an evolved Internet that can be reached out and drawn on. The development of Mix was powered by Neo4j, a graph database technology used in the backend of the application at GraphConnect 2014.
