SELinux Coloring Book was a huge hit at the Red Hat Summit last week in
San Francisco. We gave out around 1000 coloring books, and people
seemed to enjoy them and actually learn some stuff. Máirín Duffy has
setup a git hub site where you can download the source and do
translations.

Or you can print it directly from

These books are based on the article in opensource.com
http://opensource.com/business/13/11/selinux-policy-guide
which won a Readers Choice Award on opensource.com.
I find it an easy way to explain Type Enforcement, MCS and MLS Separation.
