I started a new project (shit I have too many...) that involves triangulation. This serves as a nice intro into some of the problems with triangulation (ie syncing clocks, moving sources, clock drift, etc).

Granted my application will not need atomic clocks, but you need a really fast sampling time when the object is only a couple inches from your sensors.
