PROGRAMMING:
One of the first things I tried to accomplish in pure data was building a simple cross fader between to moving images. I knew that I would want motion detection to be incorporated into my final installation, however I thought it better to start simple given my introduction to visual programming languages. You may load your own media into the patch.
A second iteration of the patch utilizes the camera on a computer to sense movement and trigger the cross fade/dissolve between the two videos. Again, you may wish to load your own media into the patch.
With several iterations in between, I was finally able to build a patch that performed the basic function needed for my installation. This patch utilizes an ultrasonic motion sensor and an arduino to measure the distance of of an object--the viewer--to the screen where the images or videos are projected and responds accordingly: The cross-fade is triggered by the distance of the viewer. The following is a rudimentary version of what I hope to achieve in a larger installation context that more thoroughly considers the various behaviors of the viewer. I've also included the modified ping sensor code for reference. Again, please load your own media into the patch.

PROOF OF CONCEPT
The two videos below demonstrate both the implementation of the installation concept and artistic techniques. The first documents physical interaction with a the screen using my final pure data patch. The second records an experiment shot on at a high frame rate that utilizes steam and a macro lens.
