Oh, hang on, my brain is slowly starting to function. (I'm far nearer to this bottle of wine than the top). However I'm struggling to find a mains-powered version of that teapot-thingy. I doubt that there's much of a market for such things, so you might be out of luck. Sorry!
"Twinkle, twinkle, little bat!
How I wonder what you're at!
Up above the world you fly,
Like a tea pot in the sky.
Twinkle, twinkle, little bat!
How I wonder what you're at!"
Tell you what, life's full of mysteries, isn't it?
I quite like that one Chris, sort of quirky but wouldn't look out of place in a kitchen/diner, you could adapt the first polyresin one by opening the back and fixing a nightlight unit inside but the shading from the pot might mean the light didn't go off.. I can't understand why anyone would want to though.
