This is an initial experiment using the kinect to generate a 3D vector field. This would not be possible without the efforts of the OF team and other people openly hacking the kinect.
Some images on flickr can be seen here.
The snow is particles are a bill-boarded sprite sheet and rendered with a simple depth of field algorithm.
