Ok, I've just bought a nice sun-moon wall thingey, which I am going to transfer into my night light . More than that, I will upgrade the functionality, that is, the moon will be functioning like old night light: light up for a minute when ambient light is down the threshold. But the sun will be lighting up if hand is being waived in front of it and stay on til another wave. And I hope to finish the transformation before the year end. :)
