Really, really simple one liner but I use it a lot, and I didn't even know the function existed until a month or so back. It returns the z-axis orientation of a layer, relative to the comp camera. Divided by 5 here, but change this number to suit your style. Positive means it faces the camera, negative means facing away.

 

When do I use it? To drive the opacity of a screen object on a device, usually a mobile phone. So you've got a nice 3D rendered spinning phone, doing the usual spins in space, flipping this way and that, and some separate screen content, showing off some feature of the device's UI. You want the screen to be 100% opaque when it's facing the camera, 100% transparent when it's facing away and have a nice fall off when it goes past around 70°, so it looks like the screen content is dimming as the viewing angle. This does that. Change the 5 to control how the angle affects the brightness of the screen.

thisLayer.toCompVec([0, 0, 1])[2]/5;

Slick. I will definitely be trying this out the next time one of those projects is in.
