Palantir is a small project developed by a group of Facebook engineers - Jack Lindamood, Kevin Der and Dan Weatherford – at a Facebook Hackathon contest. Apparently the name derives from some Lord of The Rings mythology (but of course).
Anyway, the project seems really interesting, and it is basically a video showing Facebook users interacting all over the world. The images don’t do it justice, you should really watch the video.
Facebook currently says it would be interesting in making this into a real product, but that for now it’s not on schedule. Let’s all hope this sees the light of day.
