Not tried using expressions before, so in the interest of speed and editabilty? i wanted to control the whole animation just using an expression slider and a simple formula

thisComp.layer("xxx").transform.position-time*-transform.position[2]/2

Using the position in 3D space I was able to have AE determine the speed of the object to create a parallax effect

The – as to change the negative values for positions into positive, prob could have been made simpler but I was just guessing at valid variables and it seemed to work for me
