I've finally finished the spotlight and I've used it as an element in this wallpaper created for Ubuntu Studio, the linux distro I use. It's an ubuntu derivative focused on multimedia (audio, video and graphics) that includes a realtime kernel for audio.
I've also used the jack I made for the icon posted some time ago.
Everything has been created using inkscape, blender and the gimp.
If you want to download it, you have a bigger version (1680x1050) in the Galleries, Wallpapers section.
Bye.
