What colour are the spots between the squares? Black or white?

What do you see when you first look. (The image is Copyright Archimedes-Lab)

What do you see?

What does it stops him?

What does the bar go through?

What is Da Vinci painting?

What kind of a pool is this?

What kind of a shelf is this?

What you see is limited by you.

When you concentrate, corners disappear :) (The image is Copyright Archimedes-Lab)

Where are these guys standing?

Where are these holes? :)

Where are these people walking?

Where do the prongs go through?

Where do these boys ride their cycles?

Where does the train travel?

Where is the baby?

Where is the green side back or front?

Where is the ladder leading?

Where is the man standing?
