These adorable little creatures are called Mood Beams. These are portable mood lights that are in the shape of little creatures. They can cycle through colors in a variety of color combos which include heartbeat, rainbow, strobe, color dance, and color hold. I think the more interesting feature is that it they are sound sensitive. This means that they can change colors with the beat of your music. What can I say, I am a sucker for cute gadgets that sequence lights, and they are only about $18. You can also pick all four up for $65.
