This light, is a "magical" Dragon's Egg, just ask our granddaughter, and she will atest to the "magic" properties.
Of course it is just a nite-light, which runs from a rechargeable battery, concealed inside the shell. The light will run all night, constantly changing colours, and fill the room with a delightful sleep mood.
I have tried to capture some of the colours, just need to be quick on the shutter button.
Curiosity, got the better of me, and I did dismantle the Magic Egg, just to see what was inside to give it the colour changes. There are 3 LEDs, red, blue, green, and it is just the time-on and mix, between each of the LEDs that make all the wonderful colours.
The light (or lamp) sits in a cradle, which is also the charge receptacle. So after a night of brilliant colour, we just let it charge during the day, ready for the next "dream session"
