Kids' bedroom a touch on the beige side of life? Deliver a blast of pure technicolour into the otherwise monochromatic corners of your home with the Rainbow in My Room colour projector, a device so brilliant its inventor should be awarded the MBE forthwith.

Here's how it works: A series of small Light Emitting Diodes contained deep in the projector's arc shine their pure, clear light towards a unique reflective surface, splitting the light into its constituent visible components and beaming it high onto the nearest flat surface. We recommend a wall for this task, though you may wish to use your little brother or some other inanimate object.

As well as generating a beam of pure colour, this device is clever, to boot. One can activate and deactivate the rainbow on demand simply by waving one's hand under a special sensor located on the projector.

Complete with two modes (one which turns the rainbow on one colour at a time and another that turns the whole multicoloured light-show on at once), the device boasts an admirable environmental consciousness. To conserve power, it has an auto shut-off function after 10 minutes of rainbowness. Bless.

Now, with the awesome power of nature at your disposal, you may create rainbows on demand. Go forth, and be god-like.
