CheerLights is an internet of things project by @scharler to synchronize lights to
the same color at the same time all around the world. You could only tweet
the color you want and @cheerlights, then all the devices that use the
cheerlights API would change its color at the same time. It is amazing to share
a light color with people all around the world, and it makes me realize that how
easily people could be connected with each other. For me, it is a warm and
lovely IOT invention.
