This is a real out of the camera image!
It might be hard to imagine that this is not some Photoshop creation but here it is. In fact here's how I made it just in case you are curious.
I placed a clear marble (with imperfections in roundness and clarity) on a small pillar of magnetic balls. I then draped my camera in Christmas tree lights, the old fashion kind with lots of different colours. I strategically positioned a small mirror behind the subject to create some additional internal colours and finally I made the shot wide open at f/2.8 to get that glorious bokeh in the now reflected background.
So when it comes to getting creative it is amazing what a little experimentation will provide.
