Travis Feldman received twice his funding goal on Kickstarter for his cool Molecule Synth, an electronic musical instrument that comes with various hardware modules that you can connect together to create new sounds. You can check it out at Maker Faire New York.

The Molecule Synth offers the elemental components of a traditional keyboard synthesizer — a speaker & amp, a sound generator, and a pitch controller — but presents those elements as pieces that you arrange (and rearrange!) in various combinations to create your own musical device.
