Macos – Is it possible to change the transparency of an already open window in Mac OS X

macosopacityterminalterminal.apptransparency

Specifically, I'd like to change the transparency of an already open Terminal.app window. I know I can change the settings and then open a new window, but I can't figure out how to make an already existing window transparent.

And no, I'm not interested in switching to another terminal program, thanks.

EDIT: OS X 10.6.4 (Snow Leopard)

Which version of Mac OS X?

In Terminal.app, if you change the settings of any of the presets it will affect all open windows that use that setting. (I can confirm this for 10.4+)

So, if you click on the preset you used for the open Terminal window (most likely the one with Default in grey text below it) and go to the Window tab you can click on the Color picker under the Background header and change the Opacity.
