3-D input device

I mentioned this 3-D capacitive input interface for Arduino (on Instructables.com) in class yesterday. It’s basically one corner of a cube with the 3 sides covered with aluminum foil, attached to the Arduino using shielded cable and a couple of resistors. It claims to report the distance of your hand from each of the three faces of the hemi-cube, so you can those as x, y, z coordinates to control… anything! One idea that springs to mind is setting the R/G/B values for your mood lighting. If it’s accurate enough, you could also try to hack it into your favorite cad program (you *are* already using VR goggles for that, right?)
