Today's challenge was to take a photograph on the theme "Electric".
I was short of time and inspiration today, but earlier this evening I spotted my old plasma ball, sitting neglected in the corner of the room. I managed to find a power supply for it and fired it up. Now this is electric! Electric in the sense of current passing through the plasma, and electric in the sense of excitement.
Here I intensified the patterns in the background by putting a hand behind the globe; this drew the plasma filaments to the back, covering the back of the sphere with these wonderful, organic shapes.
