billboarding

I am trying to make an Axis Aligned Billboard with Pyglet. I have looked at several tutorials, but they only show me how to get the Up,Right,and Look vectors. So far this is what I have:

target = cam.pos
look = norm( target - billboard.pos )

right = norm( Vector3(0,1,0)*look )
up = look*right

gluLookAt(
          look.x, look.y, look.z,
          self.pos.x, self.pos.y, self.pos.z,
          up.x, up.y, up.z
         )

This does nothing for me visibly. Any idea what I'm doing wrong?

I've had some experience with Pygame, but there seems to be a lot of buzz around Pyglet these days. How do these two libraries compare? What would be the advantage of using one over the other, both in features and ease of use? Finally, would you say that one is more Pythonic than the other? >>> More
