How do you react to this flash animation?

I don’t know about you but it completely creeped me out. My reaction is almost visceral in its intensity…

It is one thing to read an an article speaking to our fear of snakes and spiders that “Certainly there are certain stimuli that are pre-wired in the brain because they have been perennially dangerous to our ancestors” – but one would think that our “higher order thinking” would be able to override such basic instincts. But not so. I know this is just a bunch of electrons on screen but boy is that guy hard to bear.
