One of several versions of ‘mitochondria in action’. This has been one of my most successful themes, although this one is not a particularly good one. As Picasso once said, I often paint fakes. The colours are the same in principle, but quite different in practice. The final result depends on the thickness of the silk I used, the type of paint, the amount of light in the room when I was painting it. Some of the mitochondria in action have a lot more force in them than others. There are also a couple of ties out there with this theme, but very few indeed.
