What follows is a personal fantasy:

on mouseUp
    set the roundRadius of parameter 1 of graphic "WONKY" to 0
    set the roundRadius of parameter 2 of graphic "WONKY" to 0
    set the roundRadius of parameter 3 of graphic "WONKY" to 50
    set the roundRadius of parameter 4 of graphic "WONKY" to 50
end mouseUp

SADLY, it is ONLY a fantasy . . .  :(
