In fact, I am not a ubuntu fan (prefer Pclinuxos and KDE). This was an attempt to create some nice but original wallpaper for my sister which could provide high contrast background for her desktop and was first intended for the Vinux remaster (Ubuntu remaster for visually impaired). I did not upload it
first but now realized that someone could appreciate such wallpaper.
It is available in HD resolution both in wide and standard screen ratios.
