The newest version of Omnigraffle for Mac OS X ships with jjg’s visual vocabulary as a palette. How cool and very useful. Upon surfing a bit from a link I found at Webgraphics, I also found that Michael Angeles has a downloable palette that can be used for wireframing with Omnigraffle. Finally, there are even more palettes linked from Omni’s extras page. I have a feeling that I will never regret licensing all of Omni’s software a couple of months ago.
