Here is a gadget that turns your plants into smart lighting fixtures. The Glowze is circle shaped and waterproof. It comes with 10 RGB LEDs and a rechargeable battery that lasts up to 100 hours. You will be able to change the color of these lights from your iOS or Android device.
Glowze has a magnetic clasp that should work for most indoor plants. It lets you link up to 10 devices in one chain. Expected to ship in September. More info is available here.
