Here comes the whatchamacallit project, an interactive web app allowing for easy the creation of knowledge tags.

The premise is simple. The community tags objects they can identify around town. Curious passers by use The QR code to learn something.

How it works: Users enter a destination URL and selects a background. The app creates a downloadable png with QR code that is ready to print. The user has the option to pin the labels location on a map. They can also join the community in creating their own squares or voting up other squares on Facebook.

Try the beta at: interactivebubble.
