This is my concept of a basic snow globe that Santa would have in his workshop.
My autistic son asked before Christmas how does Santa know if you have been naughty or nice? i responded with that Santa gets a snow globe when you are born with your name on it.

I told him that "when its green that means you have been good, red if you have been naughty and yellow to make a good or naughty choice...."
Being autistic my son needs a visual aspect to understand and so this was born from it. I have a small submersible LED light with a remote designed for a fish tank cut out or a base that has no hole.
a quick tinker in tinkercad and you can add your child's name to the the plaque on the front.
The top is just a basic top with 4 points to slide in and rotate into the base.
