I had not heard of that before. I took a sheet of aluminum foil, poked a tiny pinhole in it using a bulletin board push pin, and looked at the sky through the pinhole. The moment you shake the pinhole, filamentary structures appear. The moment you stop, they disappear. Awesome! Also, great info on cephalopod eyes by comparison to vertabrate eyes. Great job!!! And very entertaining too.
