Sweet UI, but even tho it's FOSS, I bet they are relying on a centralized company server which holds all of those images and metadata etc. Worse yet, they might even rely on a third-party api from imdb or wikimedia etc. However, if they use an open, distributed db for all of that, then man the world has a killer app right there.
Kinda like google maps vs OpenStreetMaps (OSM).
