This is just like that 100 killer templates topic, 'cept nutang's service is free. Pick a design online and switch it with a click of a mouse. You can edit everything online on a control panel, and get a short url too.

Unlike other free services, there's no banner here. :D

Check it out, and tell me what you think. New designs added monthly.
