Just had some fun combining Dot TK’s TweaK API with Google App Engine’s XMPP support.
The result is a jabber-bot that you can talk to. In most cases it wont understand you, but if you pass it an URL, it will shorten that using Dot TK’s TweaK.
Go to http://tweakbot.tk/ and ask the bot to invite you. After accepting the invitation, have it rename some urls for you!
