If you are in CS3 or CS4, search your effects and presets search for seperate x, y, z position. Then, make your layer a 3D layer, apply this preset. Then go to the z position in this effect. Apply the expression, index-1 . Then duplicate your layer and turn the shy switch for the layer on. Duplicate is a bunch more times, perhaps 10 or 15. Basically each layer will be 1 pixel back in z space, so when it is viewed from the side it will give the illusion of depth. You can turn the shy switch for the comp on so you don’t have to see all of the layers. To sell the effect it sometimes helps to have a light in your comp, or turn a bevel alpha on all of the layers behind the first layer.
