Experiment: take a piece of paper and put it into a microscope. Take one of those low power pocket lasers and aim at paper from above. Then look into objective-lens (don't be afraid to hurt your eye, laser reflection is to weak to do so). Now the science begins -- no mater how unfocused image of paper surface is, you will always clearly see a granule patern of laser light. More than that it will move-morph within itself as you change the focus. You can see that in video -- at the beginning it is very close to focus length and then moves far away.
ps.: there is realy no need for microscope to see this effect, you just look very closely at the laser mark on your wall. I just used more elaborate way to capture this phenomenon ;)
Oh, is that ever annoying.
