Created with Ultrafractal. This is a single frame from an animation set I've been creating for someone. Of necessity I've kept to something simple as they want a full 1/2 hour at 30 frames per second at DVD resolution - fortunately they're doing the rendering themselves, I'm just creating the parameters and test rendering at 200*150. In creating the frames I was reminded that often using both "inside" and "outside" can be very effective though most images stick to "outside" only and so decided to render the best frames as static images. Standard z^2+c Julia with just 2 layers but using "inside" and "outside" together adds quite a lot to the result.
