I only bothered to hook it up to a lame chat application, but the widget is demonstrated. Tomorrow I may have a go at hooking it up to an actual game. Faucet's classic use was for a text adventure and had the top-left pane used for a description of your location, the top-right pane used for a list of what objects were present, and the bottom pane used to display command input and the responses they generated, as well as other game output which arrived asynchronously.
That's probably it for screenshots for a while. If you're really interested, the code's in Twisted (mostly in trunk, a little bit in a branch - exarkun/scrollarea). Check it out. Write some cool widgets.
