Well, the normal should be the "up" vector of the disc, right?

What you could use <shameless plug> is my Look_At-Macro </shameless plug>
which returns the rotation vector needed to rotate the -z direction towards
the given position/vector. So
rotate Look_At(Insert_Normal)
should work when the top of the sphere/disc is facing -z.

There's also a macro called "Orient" or something within the
POV-Shipped-Includes, but I'm the self-made guy, so I can't help you much
with that...

Regards,
Tim
