Infinite door animation optical illusion

This is optical illusion type animation.

Opening the doors (windows, as you wish) to something or the doors will never open? Checking the mood. An optimist sees here a great many of opportunities, pessimist – a lost chance and hopelessness. And I believe that the right door will be opened for sure!

Play some relaxation music, keep calm and look to this hypnotize illusion. I hope you enjoy.
