how to set mac desktop background as working terminal

I would like to set my background to a working Terminal window even when I minimize all applications. I would like to be able to write commands on desktop but I don't know if it is even possible.

I have done some Google searching but I could not find any clues. If this is possible, could you explain the process of setting it up?

I am using Mac OS X 10.7.5

Solution 1:

You might to want to checkout this tool called GeekTool as their site states:

GeekTool is an application for Mac OS 10.6+. It lets you display various kinds of information on your desktop via 3 default plug-ins

Solution 2:

iTerm2 in fullscreen does what you want. At least it does for me when I reboot when it launches on boot.

In iTerm2 you can define different window styles. I have only one defined (fullscreen, toggled with a key combination ⌥ Opt+Space). If you don't set a toggle you get a non-standard fullscreen window (chrome-less fullscreen). If you manage to get it under all other windows you get what you want.
