  Why? I use multiple scale commands a lot! ;) But multiple normal 
statements *really* seems silly... only the last counts! :)

  To achieve what you want, you need a normal_map with entries at different 
scales. Take a look at the manual (6.7.2.2), and experiment with different 
patterns, both for the normal_map pattern and for the map entries.

  And don't forget to use HQ antialiasing or focal_blur.... :)
