Spirogram - Spiral Encryption

Spirogram was the second feature (after Utopia) to be singled out on Dan Zen. It claimed that you could quadruple your visitors by adding a Spirogram to your site.

Spirogram lets you send spiral encoded messages and send them to people who then come to the site to decode the messages.

Although the campaign was targeted the Web masters to pay for a Spirogram, Dan Zen visitors could also use the Spirogram on Dan Zen and many have.
