What im doing is essentially making a strand of DNA. ive got my spheres as 
molecules of A,C,G,T and a bar connecting them.  They are being generated
by a while loop.  Its all working fine but i cant rotate them properly.  

i was trying to use a rotation and then a translation to get the 2 spheres
and bar in line with the rest of them but that will only work for certain
angles and then i would have to figure out the translation again.

Anyone have a  general formula? Im looking for some sort of sinusoidal
equation i think.  Just cant put two and two together.

so if the camera was directly atop the strand of DNA and the desired angle 
was 90 degrees it would look like this

i know this is damn confusing.  if anyone wants to see the source let me
know and ill email it.

Thanks so much
