Begginning with the specs:
Modeled in Blender 2.58 and rendered in OctaneRender™ as usually. Whole render is computer generated which means there are no photo textures, photo backgrounds (like HDRI) etc. Raw render took about 30 minutes with its over 2500 pathtracing samples.
Created mostly for fun as well as benching my new GPU.
PS. Of course the wallpaper is available in 3 different screen resolutions; 1920x1200, 1680x1050 and 1440x900. Also available with logo and my personal sign, sign only, and raw render only. Click on Download button and choose your resolution and version there :)
