The creators of this video and project describe it as a "game," which it isn't, really, but it is really, really cool: you make a sort of extra-firm Jello-like product by mixing water, agar agar, and some food coloring (optional, but why wouldn't you want your final product to be blue or pink?) in a mold. After it firms up, you put it on the "game board," actually a capacitive sensor with an embedded Arduino microprocessor, which detects different kinds of touch on the Jello mold and converts it into theremin-like noises. Fun (and a little appetizing)! Video below.
We've covered theremins before, from DIY pocket theremins to hacks using the Microsoft Kinect and Nintendo Wii. But we've never covered a utensil-based theremin, or a theremin with tines, or even a theremin that uniquely reacts to the texture of chicken skin.
Today in Microsoft Kinect hacks, we've got quite possibly the first musical instrument to be transformed into a gesture-controlled facsimile of itself. It's one of the only instruments that can really be brought over without losing either the method or the soul of the original, since the original instrument is played with gestures in the air as well. I'm talking, of course, about the theremin, the favorite instrument of nerds worldwide.
