How can you see anything that isn’t there actually?
It is the core question of Think Invisible. Circles give deficient contour of the pictures - that’s the simple method how we make hundred-times-seen pictures interesting again.
It is not the magic that lets you recognize the whole design, but your mind.
This tricky illusion of the contours intentionally shows important details, and hides all the rest. Since what matters is invisible.
