the pad needs to be reflective. otherwise the light isn't
reflected in any meaningful way. Try crinkling up a piece
of tinfoil and then unfolding it and pressing it flat around
a piece of cardboard. The remaning marks in the tinfoil from
the initial crumpling should do the trick. make sure you
crumple it enough to get decent resolution.
I find that this works pretty well for vertical motion, but
not so well for horizontal on my type-4 mouse. fortunately
I've got a regular mousepad.
