Mark,

You  may be able to guess what my  solution might be; that's right 
Turtle Graphics.

on mouseUp
   startTurtle
   put 12 into tNumSpokes
   put 100 into tLengthSpokes
   repeat 360/tNumSpokes
     forward tLengthSpokes
     back tLengthSpokes
     left 360/tNumSpokes
   end repeat
   stopTurtle
end mouseUp


Paste this handler into a button in the stack:

go url "http://home.infostations.net/jhurley/StopTurtles.rev"

Or if you want something like the clock in your graphic;

go url "http://home.infostations.net/jhurley/Build_a_clock.rev"

There are lots of variations possible.
