Avatar - Unobtanium Office Desk Toy

I was thinking about this the other day and I though "someone on TheRPF must have made this already".



I've had a search on here (admittedly a very quick one as I'm strapped for time at the minute) but found nothing.

It can't be that hard to make can it? We've done floating globes, spinning tops and coca cola bottles, all suspended by the power of magnets. Surely the maths is there to make this work?

@Prop-Builder did some work on it years ago, and I am eagerly awaiting that... but I would love it if someone else like *cough* @Rylo
took a stab at it
I have had a piece of Unobtanium/Galena for years, and been waiting for this awesome Avatar prop
