After, creating a Tron identity disc from the Pclinuxos logo, I came to the idea with sharp steel circular blade and the term “bleeding edge” used for top and hi-tech things. According to me, this goes well with the dark design and the metal textures, although I do not like dark or violent/brutal wallpapers. This is rather meant as allusion to “bleeding edge”.
The metal textures were taken from PSDgraphics.com [link]
All work was done in my favorite programs Inkscape and Gimp. Wallpaper is available in HD wide resolution 1920x1080 pixels.
