And extreme aspect ratio (40:1) render of a 1024X formation I found within the Mandelbrot set. Locating the centroid of such extreme features within the Mandelbrot set can be a pain, and the "Find Centroid" checkbox in Mandel Machine often fails. Rendered at 102400x25600, scaled to 25600x640 for 4x4 antialias. Due to the extreme aspect ratio, I have only uploaded a preview render at 1600x40. For full view, please visit my deviantart page:
