looks like you are a person who would appreciate these small visual
enhancements:
mydialog = CreateDialog[
myflower,
Modal -> True,
WindowSize -> All,
WindowMargins -> Automatic,
WindowFrame -> "Frameless",
WindowOpacity -> 0.75,
WindowFloating -> True
]
I think WindowOpacity will not work for all OS.
For me the code you posted didn't work right away, and I think this is
because the Module doesn't behave as you wanted. It think when stuffing
constants into a Dynamic the use of With is usually the better choice:
With[{
w = 0.22,
bigD = 2,
d = 1
},
Dynamic[...]
]
