I got standard Ubuntu Gutsy installation on my laptop. Some time ago I tried Ubuntu Studio and I always remembered its look. It was probably one of the best looks of Linux desktop I ever seen. It turns out that guys from Studio made they distributions look pre-packaged and you can use apt to install it. It is just one simple command
sudo apt-get install ubuntustudio-look
And results are:
Fancy a little bit of Studio for yourself?
