Two security researchers with artistic tendencies, Srikwan & Jakobsson, have created a "set of cartoons":http://www.securitycartoon.com to educate users on a wide variety of computer security topics. I think they tend to be a bit too focused on scaring people into awareness, but they do have some really good content, delivered in a comic style.
