The Circle Guitar
The Circle Guitar sort of looks like a regular guitar, but it’s controlled by a spinning wheel with 16 individual magnets that strike the strings. It allows for rhythms you could never produce with your hands. You can program and sequence the notes on the fly—including how hard they’re played—and since your second hand isn’t strumming, you can play chords with all of your fingers, mute strings in innovative ways, and otherwise manipulate the guitar using unprecedented techniques.
