Maya (the 3D animation software) has had a radial menu with a gesture feature for as long as I can remember (4.0 I think). The beauty of it is that you can just use the menu slowly, or as you get familiar with the movements of your mouse (or stylus), just draw the movements and be done with it in a matter of seconds. I've seen a friend of mine working on a detail model 7 years ago and he wasn't even thinking what he was doing. Just naturally drawing the path to the option he wanted (and god, the maya marking menu is damn full of options and context sensitive even) and boom, job done. The ux for a Radial Menu (or also called a Pie Menu) is incredibly intuitive and allows for beginner and power user usage.
