Cool shape! :-)

Yep, isosufaces are sometimes more flexible and faster than other 
shape/surface options! However, as with most things in POV-Ray, where 
they work best depends greatly on particulars.

Note. IIRC, the f_rounded_box() function has a changing gradient outside 
everywhere and into the rounded box only to the rounding radius - after 
which the returned values become fixed 'inside.' This makes the function 
difficult / impossible to use in many more complex situations. In other 
words. it's a function which can be difficult to use other than as a 
stand alone shape(1).
