I've seen this on a number of graphics packages (Maya for example)
and it does work quite well.

The idea is that when you Right-click in the image to pop up the
menu, instead of having just one honking great list of stuff, you
split that menu into a number of catagories (4 or 8 typically)
and scatter those catagories as little icons or perhaps text
labels in a ring around the mouse pointer.  Moving the mouse a
short distance in the requisite direction pops up either a new
(short) menu - or (more likely), drops you into a new ring of
catagories.  Releasing the mouse activates whatever thing the
mouse is over at the time in the usual way.

The idea is that a right-click followed by a short (and easily
memorized) "gesture" gets you to the menu item you want in
less time than scrolling down that l-o-n-g menu.

It's pretty logical actually.  Encoding the function you want
as a 1 dimensional list requires EITHER tiny fonts and accurate mouse
positioning OR large fonts and huge mouse movements.  Neither are good
for speedy menu item selection.  Using (in essence) a 2 dimensional
menu allows for larger, clearer fonts with less distance to travel to
get to the entry you want.

It also seems that people are somehow able to 'learn' the gestures
to get to certain items quickly without even reading the menu's.
It's like changing gear on a stick-shift car - you don't even have
to think about the actual motion.  "Right-Click then move up then
right then up again" seems easier to get into "muscle memory" than
"Right-Click, move down 1.3cm then move right then move down 2.6cm".

I think the DISADVANTAGE of this scheme is that the beginner
doesn't see a clearly presented *list* of options - this is
perhaps a problem - but it could be a configuration option to
select which style of popup menu you want - and in most packages
that use these gesture menu's, there is also a standard menu
containing all the options in the usual place at the top of the

I saw a demo of one of these systems where a joystick was used
to select the menu item - with the idea that you could mouse
with one hand and pick menu's with joystick with the other.
Dunno about that - I like my hotkeys.
