golden spiral 6 icon png download

Golden spiral sketch. Eventually ended up with this image from the series: http://lazururh.deviantart.com/art/golden-spiral-3-659167553. This is a base step of that drawing. Although it might look fancy enough as is, for practical reasons it got way too complicated and probably worth a reconstructing from scratch for new "variants" and further improvements. Apart from that, the steps are alone worth sharing. A gradient map is used to map the complete rgb hue spectrum over a gradient mesh spiral. Thumbnail generating won't work on it unless the renderer (0.91) updated.
