  • Count the black dots. Do they keep moving?
  • Are the purple lines parallel or curved?
  • What do you see on the left? What do you see on the right?
  • Can you believe that all the gray lines above are perfectly parallel?
  • Stare at the blue circles and move your head back and forth from the screen. Do the outer circles move?
  • Can you believe that this is a picture and not an animation? To check, just focus on one leaf for 5 seconds.
