Two stereoscopic views of Instrument Nine in action. The shadow of the rhino sits just off the screen. The shadow of the shadow maker floats in front of the rhino (see the parallax between the shadows on the rhino’s rump). Both are quite subtle distances off the intended screen. I will make some tests to see how far I can push them without getting eye strain, the problem with the first iteration, Instrument Nine (a).
Below is an overall view of the instrument.
