This one is very similar to the discussed above. They call this one the Rainbow Over my Bedroom. Slightly different name, and the exact same concept, only designed a bit differently.
This one also uses multi colored LED lights, and is very easily operated by children. It takes 3 AA batteries. One knock on this one is the fact that it does not project to a large distance, so it is not ideal for a situation with vaulted ceilings, or any other high imaging target.
