It's a processing software which use graphical /visual programming a little bit like Virtools.
This soft has been massively adopted by artists for numerous applications including visual processing like DJeing.
I'm currently working on a little patch to manage head sensors and provide accurate rendering with OpenGL. This pre-pre-pre- alpha version use euler orientation (== evil due to gimbal lock) but will use quaternion as soon as i found a solution to use them inside Max, cause there's currently no native support.
But it'll not be a big deal.
