Watching a gnat while listening to 'Good Vibrations'

I've probably seen gnats thousands of times, but I don't think I've ever SEEN one before. Know what I mean?

This thing is tiny. It wouldn't crowd a pinhead yet it senses its surroundings, seems to get to wherever it is it is going, can FLY, land and walk.

It's nervous system can't have that many nerve cells, but look what it does with them. It is an autonomus, living thing that is just amazing.
