  1. Magnificently creepy and cool. Posted 11 days ago
    1. I wonder if its learned behavior to find it creepy. It's just an eyelid. But I do find it creepy too. Maybe a Hollywood effect, a typical alien in human form would blink this way :) Posted 11 days ago
      1. So true. It’s only creepy because of perception. It reminds me of a zombie ;) Posted 11 days ago
  2. Ha ha.. Where's the snooze button!
    We get these every day... plus that ringer Currawong which I find even creepier close up.
