While this gadget might look like a Nintendo Wii controller, it's actually the Withings Beamo, a sleek and simple-to-use at-home health monitor that's part digital stethoscope for listening to your heart and lungs, part thermometer, and part ECG reader.
(Note: It's also a blood oxygen saturation (SpO2) monitor, but this feature is not yet available in the U.S.).
