I've been working on a fun little app that paints geologic maps over landscapes using augmented reality. You can use it to identify what the mapped rocks are, read descriptions about them, and view the earth as it looked when they formed by turning back the continent positions. It spun out of some augmented reality work I was doing on my other side project app - Flyover Country, which tells you about the view from the airplane window.

A few top-level comments from Hacker News, shortened. Read the full thread on Hacker News.
Very well done. The animation of plate movements give me a real sense of vertigo!
