Great idea! Or swing the laser as a pendulum!
But why reflect the laser *off* the camera? The laser just needs to
shine directly on the wall in one place (or swing on the pendulum). Let
the lens do the shaking. Reflecting it off the camera may reduce or
change the trace. E.g., both the mirror and the lens move up, and the
laser motion reduces the variation on the film.
