Darn, haven't learned arrays yet. What would I do with the array?

I thought I had to encase Obj inside it....

Put your spheres in it and loop over the ones you have so far looking for
a hit with trace(). Then take the closest hit you found. The nested unions
are probably faster, if you can get them to work.

You're looking for "object" rather than "#object". "#object" is bad syntax,
but the parser treats it like "object" for now.

Worse, the whole system freezes. I'm currently using a Macintosh for this.

Then I'll try using union when I get home, since that computer is a PC.

Neither here nor there but... CodeMax syntax highlighting sees keywords
without the "#" and yet POV-Ray doesn't parse them okay; as expected of
course.
