63 hours? some of my IMAGES take that long. Most animations take MONTHS! I WISH I could do a good one in 63 hours! shheeeesh!

I once did a still render of "Aquamarine" http://website.lineone.net/~dave_makin/fractal_art_5.html at 8000*5000 in Ultrafractal as a disk render with oversampling set at 3*3 and it took a month

Well I don't really wanna give away the full parameter set for Aquamarine, but here's the base layer - just try some different colourings out
The details of the original are given briefly here:
