Meet the Lightcast: an innovative light bulb with speakers built into its center. You can use it to play your music or connect it to your smartphone to turn it into an office intercom. Alex Lieberman is the inventor behind this cool idea. The device connects to the Wink app to get the job done. It also has a microphone. The Lightcast is made of plastic and metal and does not take a whole lot of space. Yet another cool Quirky product.
