Hmm. POV-Ray description files could possibly handle step-wise construction by
playing with the timer (clock?), a feature used to produce animation files.
I haven't played much with POV-Ray since I took up LDraw, especially not
authoring files, but I believe it would look generally like:
<step-1 parts>
if timer >= 2 then
<step-2 parts>
if timer >= 3 then
<step-3 parts>
etc., etc.
