Smart lamp 'paints' light in any direction you like
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.
