I came across this multi-colour LED projector light and it actually has a lot of features for the price and it looks really nice.
You can change the colours, turn on/off the night light and even turn on the automatic rotation of the lamp.
The device can be powered up either using an included DC to USB cable or 4xAAA batteries.
Everything else is pretty much self-explanatory and it all depends on your creativity where and how you put the lamp, the lighting conditions you are in and so on.
All in all, this multi-colour projector light is a pretty cool yet cheap gift for almost any occasion.
