Smart lamp 'paints' light in any direction you like

A Vienna-based startup named Luke Roberts is releasing the Luke Roberts Smart Lamp. It's an Indiegogo success that lets you cast light of any color in any direction by picking a shade in the companion app, then swiping your finger across your phone's screen like a paint brush. Though it isn't cheap, it's a pretty impressive product with plenty of color-changing horsepower. Inside are over 300 light-emitting diodes -- for comparison, a color-changing Philips Hue LED only has a few dozen.
