  I've often thought of that one, but it smacks of that discussion a
while back about the robotic lawnmowers.  What happens if it confuses
*you*, or some part of you, for the bug?

  The lasers are presently hard to come by with a, say, 1 kJ pulse
*output*.  If located about 6" from the ceiling it would perhaps be
little worse risk than a similarly placed ceiling fan...
