This article:
http://www.tron-sector.com/articles/article.aspx?ID=131
states "Each Lightcycle is composed of 57 geometric forms that have been
combined by a solid-modeling program."

I had made a Lightcycle that had used several hundred primitives but after
reading the above I wanted to take a shot at the challenge of getting it
down to 57 primitives.  Well I did even better then that, I got it down to
54 primitives and I wanted to share.

The code for this image is available here:
http://www.wwwmwww.com/TRON/LightCycle.pov

This is the first piece of code I've publically shared so go easy on me.
I'm far from being an expert.  However all comments and suggestions are
welcome.

Enjoy,
Carl

Interesting.
  I think you could use even fewer primitives by using lathes in exchange 
for the first two difference operations (after a quick glance). It does 
appear there could have been more detail added, though I suppose the 
computer power used to make "TRON" was rather limited by todays' standards.
  Looks like fun.

Thanks everyone. By the way, I discovered a small mistake in the code I had
posted. It's now fixed incase you haven't downloaded the code yet. If you
have all I have changed is the two places I had:

Shear_Trans(0.866025*x-0.5*y, y, z)

I replaced it with:

Shear_Trans(x-0.57735*y, y, z)

This cutout for the rear fender should have extended into the bike 86 units
to avoid intersecting the rear tire. The first transformation above only
extended it 86*0.866025 units or just over 74 units into the bike.

Sorry I didn't catch that before I posted the code.

Enjoy,
Carl

Here is the same image made with the corrected code.  The difference is most
easily seen in the reflection of the orange bike.
