Probably a version of the image rendered in CPU mode.
                                                                           I think I used this one in an animation too.
                                                                                       Its name is because it was rendered originally in 2500 x 2500 pixels.
                                                                                       Jwildfire makes nice space-like images, even the random ones.
                                                                                                                                                               The image looking glass rendered as a solid. Didn't came out as expected.
                                                                                       This is probably a frame of one of my fractal animations.
                                                                                       part of a series with nice Juliasets. They were all added to an animation file later.
                                                                           Could have been a cover art of a Slayer album
