Graffletopia

I love OmniGraffle, which is made by OmniGroup. My work colleagues can attest to my love of this application. One of its features is to install templates that contain widgets that you can use in your diagrams. For example there are templates for UML diagrams, network diagrams, family trees, etc. Well to keep up with the spirit of templates there is website called Graffletopia that contains a collection of templates available for OmniGraffle.
