Make terminal transparent to show wallpaper The opacity option of the Gnome terminal in Ubuntu had a neat behavior, which showed the desktop wallpaper instead of the other windows behind it.

Has anyone been able to make Mac Terminal, or an alternative terminal app, do this?  I know you can set a terminal wallpaper, which squashes and stretches with the terminal window.  Thanks!
This can be done simply by typing this command in the terminal:

" defaults write com.apple.terminal TerminalOpaqueness '0.85' "

Without the quotes of course. 

You can adjust the opaqueness level to whatever you like
