The mood ring was child's play -- this is for us adults.

You can program the the Morpheus mood lighting pod to change colors as fast as your moods. It looks like a high-tech light so it can go just about anywhere. You can choose colours that add warmth in winter, go for cool blues in the summer or just set it to a colour you look good in. Permanent candlelight, in my case.

There are a number of presets, so you can let Morpheus do some "morphing" - changing the colour range in your room subtly, which sounds like fun.

It's available from Morpheus Lighting for about £65, which is my way of telling you that you can't buy it here yet.
