Yah, did this in college long ago, before laser pens were common.
We used the "big" lasers. :-)
We also glued a small mirror onto a piece of aluminum foil wrapped
around the end of an open tube, and placed it outside in the quad.
Then we bounced a laser off it and got it aimed at a special LED
for receiving the laser, with the LED hooked up as a mic through
an amp. Worked pretty good, we could hear everything that was going
on around the tube we left outside.
