ok, here's what I made: the logo from www.rhymbox.com.

Can someone tell me why the yellow rings don't render smooth? they're extruded nurbs curves and in the working viewport they look nicer.

Also, I'd like the gray triangle to be more metallic of color. Can someone tell me a way to do this? Still haven't learned about texturing.

And I'll add in a 3 point lighting system like in that VIP movie by Mike.
