I'm sure most of you have heard of floaters, the little floaty things in the back of your eye. While I find that fascinating in and of itself, it gets cooler. Ever stare at the clouds on an overcast day and see these little black dots flicker all around your field of vision? Those dots are white blood cells moving through your eye's vasculature.

I can't help but see them but I'ce come to appreciate the fact that as perfect as the human eye is, it's not even close. Thoughts?
