An actual 3d fractal flame, hovering over an ocean. It's actually a composite of 3 renders, one of the 3d fractal, one of an ocean at the same angle, and a 2d version of the fractal used to cast reflections in the water.
Fractal Flame image. This is how I imagine an Atom would photograph, if we could get a live action shot. We never can though, as light can't bounce off all those parts fast enough to be captured like this.
