We just launched MatchBox, one of our initial internal projects for public consumption. MatchBox is a project that aims to understand patterns and rhythms in your typing habits. This release is a Firefox Add-On that keeps starts learning your habits for you to use later. Once we’ve collected some data, we’ll be able to do some interesting analysis such as adding a layer of security to your browser based on whether or not the person typing matches your patterns, or show you a realistic “Words-Per-Minute” count, or show you how you compare to other typists of your gender/age.

You can view more information about the project here, or go straight to the download page.
