It's probably the water causing refraction of the scope.  You'll see that at higher magnifications.  I think it's the same principle as a snowflake.

I'm not an expert but the diamonds are markings for setting up your bank shots. Bouncing the white ball off one or more rails to hit the intended ball.\nBelieve it or not, there's geometry involved when playing pool and the diamonds mark the spot for the calculations that are done in your head.

When water falls, it becomes a mist. Then light refraction occurs and the wave length changes. It looks white because it scatters the light. I also creates rainbows because of the light refraction.

well, the thing that makes the water glow is called phosphorescence.  I know for a fact it is in the waters of a place called Naples, FL.  It is actually a greenish glow & can be seen at night.

The two main types are helical and icosahedral. They can also vary with size. There are also bacteriophage's with an icosahedral head and a helical tail. Some viruses have an abnormal shaped such as Pox viruses which are brick shaped but predominately it is one of the first two.
