Auto rotated layers.

hi,
i would like to know if an expression could fake a simple 3D effect. It's a bit complicated to explain but let's try.
I worked with 3dsmax and I realised that a kind of texture mapping (texture projection) allow to have a texture facing the camera all the time.
If you used to work with 3D software you know it, screen projection mapping.
I would like to use this kind of technique in After Effects, but it's not exactly the same.
In fact I would like to arrange several layers in a 3D comp, and all should face the camera. So when you move the camera, you won't see a layer with perspectives, the layers don't move but automaticly rotate, so they are 90° rotated from the camera.
You could use it in many features like neat explosions effects ... and many more. The basis is simple, but how about the expression?

A simple camera movement. The layers are in a 3D workspace.

The rotations as been made with keys, it's not really precise and very painful to setup, further more with a complicated camera movement
Does expressions can make this job easier?
