[citation][nom]icepick314[/nom]how about mood pillow?shows different color depending on how deep you're asleep?[/citation]
I'm sure the ninjas that infest my apartment would love that.
If they're lit then they'd be harder to trip on than normal pillows, which can hide on the floor if you don't want to turn the light on for whatever reason (if you leave them on the floor next to your bed for some reason)
If it's got a light in it, surely it'd be harder to trip on than a normal pillow? If you're getting up in the night, a lit obstacle course to the loo would be easier than trying to remember where things fell.
I have never been a fan of LEDs in a home. They are extremely unpleasant and unnatural to look at. The light they give off is very.... synthetic, for lack of a better word.
