Glad to see Don Hopkins mentioned, I came to this thread hoping he had seen it & commented already. I'm curious to hear his thoughts on it! I know he loves radial menus, understandably so -- they really can be quite effective.

When I saw the article about Pie Menu, I thought of Don Hopkins' work with radial menus in SimCity. It's probably (one of?) the earliest implementations of this UI concept.

I haven't actually used it, but the circular shape seems a bit wasteful of space compared to typical nested dropdown menus. Maybe a circle of icons is more suited for touch-based interface.
