Designers Mark Szulyovszky and Adri Bodor created an interesting series of works called Think Invisible Posters, in which they “hidden” images of famous heroes and characters. You can find their Bart Simpson, The Beatles, Sherlock Holmes, Jimi Hendrix etc.
“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. “
