I've been working on an app for the Leap Motion Controller built using Cinder, called Beautiful Chaos. I've finally got a short promo video put together that I'd like to share:

Basically it's a 3d strange attractor that you can control and fly around with the Leap. With two hands, the x- and z-axes of the hand movement control the coefficients of the math equations, and the rotation of the hands control how much randomness is added into the system. With one hand, the xyz movement and rotation of the hand controls the camera in a Google Earth type fashion (if you've tried or seen the Leap Motion + Google Earth integration it should look familiar).
