Winter is here for many of us, and with it comes long cold dark days. Devices designed to simulate the sun are nothing new -- there are many of them that come in the form of alarm clocks -- but Sunn Light is a bit different. Most notably, Sunn Light is big and round just like, you know, the sun. It is also dynamic, not content with merely shining warm light. The brightness level and color is constantly changing to match the sun, something said to "help your body tune" into the rhythms of nature.
