But you sill need to account for the x value, but I assume you would have
done that too.  This works, but the image will probably look distorted --
ie.  a cube will not appear to be a cube.  I guess you're also making the
assumption that as objects get further away, z goes down.  Remeber that the
further away a point is from the observer the closer it appears to <0,0>.
