Has there ever been a time when you have wanted to create a mirror image of
an object? It's easy. Here is a simple example:

#declare foo=union{
// Your Objects Here
}
object{foo}
object{foo scale <-1,1,1>}

This example will create a mirror image of object foo across the x-axis. The
key to this trick is the scale of -1 in the x axis component of the vector.
This will work in any axis. Just thought that some of the newbies here might
find this trick useful.

Us oldbies know about it but you are correct in that it is a good
time saver if you just need to mirror an object.

Perhaps a good entry for the VFAQ (although I haven't seen it asked very
much, though).
