THIRD PPC CHALLENGE - Wheeling spheres

The second PPC challenge has still got a week to go, and is still open, but I'm adding this one early.

The challenge is to replicate the Wheeling spheres animation.

Mike has shown the principle of how it works in the Wheeling Sphere  Animation Thread. Now all you have to do is put it into practice.

You can use any colours, fills and background you like, but the spheres must revolve in a circle as per the slide.

As usual, please post responses to this thread. As you are already halfway there with the video on Mike's post, the deadline is going to be tight - 8th January  - same date as the greeting card challenge (Extra kudos if you can combine the two challenges!!)

Here's the original slide for reference.

Wheeling Spheres

Um, you're welcome everyone? I'll try not to spoil any future challenges as the masked powerpoint magician.

The challenge is still open to you as well as anyone else - the video only helps partially - the hard work is still to come!

I'll try to combine both into one, but it'll be a while before I can get started.

That'll be great. Put a request for a time extension on the challenge page if you need to.
