I'm really excited about the Leap Motion Controller. I signed up for the developer program more than a year ago. You're very lucky to have the opportunity to work with it right now. I'd still love to join the development on the open source/developer community side of things. Let me know if theres any way to still get in on the developer preview. I have lots of cool stuff I could write and like zero interest in writing closed source proprietary programs to sell for money. I really just want to make awesome things. I think Leap is going to change computing as we know it for ever. Personal computing will never be the same. I haven't felt this way since the introduction of the mouse. I'm so tired of Kinect Hacks with their idiotic limitations and dependence on broad interruptible IR noise. I can't wait to get a Leap in May 

Here I have pushed some examples made using this library, if you need to get started using it with 3D models and so on.. https://github.com/hamzeen/P5LeapMotionExamples
