So we've had this plasma ball in our family for years now, but I recently realised that I'd never taken a photo of it in action. As it's still a pretty fascinating effect, I thought I'd rectify that...

I thought I might need a black background of some sort to isolate the ball, but as it turned out, simple turning all of the house lights off worked well enough. It just needed a very slight level adjustment afterwards to bring the background down to pitch black.
