Just finished up hacking on my submission for the Wufoo API contest. VoiceForms 4000 takes any existing Wufoo form and turns it into a phone survey. The app is written in Python, runs on App Engine, and uses Twilio for all the phone magic.

Go ahead and fill one of the sample forms and tell me what you think. Enjoy.
