I think humans might have some instinctual fear of being stealthily conquered by robot overlords because I totally freak out when I see things going wonky like that.
I had this Atari 800 when I was really young and we had this Sesame Street video game for it. We put the Atari 800 in my closet just because we weren't using that space. Well I had this dream that the Atari 800 would turn on and there would be Ernie's face flashing on the screen with some sort of low "boo-BOOOOOOP" chiptune noise playing over and over and it scared the hell out of me.
And today when my cell phone ran out of batteries I tried starting it up, and it played the "on" jingle, and half-way through it started playing the "off" jingle, with "RECHARGE BATTERY" on it. Nowhere as frightening as a pixelated Ernie staring at you in the middle of the night, but still like "oh man I've never seen that before that's scary."
Tell me about your scary gadgets!
Also, here is my laptop's desktop background to fit the occasion:
