I think Narcotics (at least) uses it (or has done), see this thread: https://www.pcspecialist.co.uk/forums/showthread.php?15371-Which-wallpaper-do-you-use/page2&highlight=desktop+wallpaper
It does look pretty cool, I downloaded it and then never got round to setting it up.... *lazyfacepalm*
Had never heard of this before today. Installed it earlier with one of the recommended skins, and looks pretty good so far. Haven't noticed any performance issues, but only played around a little so far.
Thanks for the inform on it I guess
