Are the dots white or black?
 

Glance around at these circles, pretty cool huh?

Look for a minute, which way are the dots moving?

Are the lines straight or bent?

How many faces?

Can you spot the man and woman within the face?

Can you see the dog?

Straight, or spiral?

Stare at the center dot and move your head in and out, wo!

Up, or down?
