Laser light projectors are the laziest way to decorate for the holidays. No ladders and no untangling light strands required. This Star Shower motion has red and green lights that dance around your house in varying patterns (watch videos of them in action) and it will automatically turn on when it gets dark.
The static Star Shower is part of an Amazon Gold Box deal today and is $20, but this one is the same price and adds motion so grab which ever one you have on your Christmas list.
