Let's see how you can customize your desktop of Debian-based distro. How would it be if you put something RainBow-like on your desktop?

If you are using a Debian-based Linux distribution such as any of the Ubuntu family, you can install conky on your system using apt package manager as follows.

$ sudo apt-get install conky

You are able to install the conky on your favorite distros and different package managers.

After the conky installation you need to install the conkey-manager. In this case, you have to Google it and find out the way you can install it on your distro.

Now, It's time to explode your desktop. Clone this repo right in ~/.conky. Now you have such a thing ~/.conky/raincon. Be awearnes you are using a hidden directory which means you may not be able to find this path at the first time. Restart your system and reopen the conky-manager, then you will be able to have RainCon right at least of your list. Turn in on and enjoy.

As always, Fork is free for you :)
