Ziggy,

Have you put a strobe on it? I wouldn't be surprised if the
displacement is much greater than your eye guesses. I've found this
with our large tuning fork setup. The ends of the fork do move an
inch or more; even several centimeters. But, to look at it with
normal light, it just seems to be a bit fuzzy.
