Launched this little widget creator today.

Users upload an image, crops it and positions it, enters their info and creates a personal ID card.
We used google app engine and django to build this. The google app engine system is really great for small projects like this.
We created two types of widgets, the main one is flash and can be embedded on exterior sites. The secondary one is just html and css for use on the home page. Both of these types pull data from a common json file to create the individual cards.
I might write up a full case study to highlight some bottlenecks and some of our solutions.
