[sf-lug] how can we use leapmotion with linux?

[Michael Shiloh]

I would be most interested in hearing about the Linux drivers when possible.

You mentioned you used an OSX computer. Are the drivers also available 
on Windows? Since I teach, I need to support all 3 operating systems.

Besides the drivers, is anything else required?

I will check out your code. Thanks very much for the link.
