Anyone would have thought I have too muck time on my hands…
This one was very much an experiment created by setting the camera on a very long (50s) exposure and running around to the front, posing, letting off the flash, running around to face the other way, and letting the flash off again.
It took several tries, and could be improved upon, but the nice thing is that it looks pretty much as I had it in my minds eye…
