I can’t get over how many amazing and inventive hacks have been created using the Twitter API. It’s as if the Twitter API is the new spray paint and developers are the new graffiti artists: constantly competing against each other to tag (no pun intended) the most ridiculous locations in the most interesting ways.

The latest Twitter hack that caught my eye is this iPhone Lo-Jack. Twitter is used as the semi-secure repository of information for where your iPhone is at any given time (can update as often as you’d like). Lo-Jack (in case your iPhone is missing or stolen) is the most obvious application for this dataset, but I’d be interested in seeing a graph of the information over the course of a year, so I could see everywhere that I (or at least, my iPhone… with decent service) had been. If you’d like to implement this hack for yourself, TUAW has instructions and a more detailed description.
