I tried to show the idea of an ibex without getting into satanism or heavy machinery. Note that non-brown colors are used
So far the idea is based on a spiral of simple dots which should represent the horns of the ibex (the most interesting part, I think). The background shows how one could use browns and other colors...needs a lot of work, really
Anchor(Palette) Palette Check http://wiki.ubuntu.com/Artwork/Incoming/Intrepid/Intrepid_Ibex_Palette_Review for the current version. Until now this idea is only roughly based on the exact colors.
