Optical Illusions 3

ESCHER'S BELVEDERE
What is wrong with the structure? This is the first impossible print created by the Dutch graphic artist M.C. Escher, in 1958. The top floor appears normal, but is in fact perpendicular to the bottom floor: impossible!


BECKONING BALUSTRADE
Can you find the figures hiding in between the columns? This figure ground illusion is by Roger Shepard, and is a variation of the more famous "faces/vase" illusion.


MELANCHOLY TUNES ON A FLEMISH WINTER'S DAY
How does the column come forward? It can't. This is another impossible image, based on the original impossible triangle illusion by Roger Penrose.


BETWEEN ILLUSIONS AND REALITY
What is peculiar about the two openings?If your cover up the top half of the illustration, the scene is perfectly possible. Look at it all together, however, and suddenly it is a lot more difficult to get into the entrances than you might think!


THE IMPOSSIBLE TERRACE
Are you seeing the balcony from the bottom of the top? Both. This is an adaptation fo Sandro del Piero's "Folded Chess Set", where perspective from both above and below is given simultaneously.


L'EGISTENTIAL ELEPHANT
Will this elephant have difficulty walking?At first glance this elephant seems to have all its legs, but look closely: none of them are attached to its body! Roger Shepard created this variation of the "impossible fork" illusion.
