Paper Signals: A Voice Experiment from Google

Super interesting maker/prototyping experiment from Google…use a few pieces of cheap hardware and paper construction to build a device that listens to your voice, and acts as an ambient information sensor. Potentially really useful for maker programs in libraries (if you don’t mind the creepy Google factor).

Paper Signals are build-it-yourself objects that you control with your voice.
