User Theo Armour came up with program that can record and play your hand movement through chrome browser.
Theo Armour :The jestPlay app enables you to record your hand movements by saving data from the Leap Motion device to your computer as JSON files. Once saved, you can open these files and watch a full 3D replay of the movements. See it here:

The app is a ‘cookbook’ style app. It is not a fully-featured or even a finished app. It does, however, provide you with a simple working example in under two hundred lines of JavaScript that you can use to start developing your own code.
