Humm, I just spent some time installing a number of Drupal Themes at the TRY O2 website, and found a couple themes that are are quite nice.
Check out how http://try-o2.com looks at the moment: (the top banner images rotates on page load):
I think that this text really encapsulates what I'm trying to do with O2:
"Welcome to OWASP O2 Platform's website. The O2 platform represents a new paradigm for how to perform, document and distribute Web Application security reviews. O2 is designed to Automate Security Consultants Knowledge and Workflows and to Allow non-security experts to access and consume Security Knowledge."
Does this text make sense to you?
