Another striking example of trompe-l’oeil, this one painted by Rex Whistler at Mottisfont Abbey in Hampshire, England: The niche, the brazier, and all the objects are painted in place on a wall in the drawing room. Click to enlarge.

The grand gallery on the first floor of the Château de Tanlay, in Burgundy, appears to bear a vast program of sculptural decorations, but it’s all an illusion — the images were painted onto the walls and vaulted ceiling by Italian artists using the monochromatic technique known as grisaille.

The room, 26 meters long, was originally longer still, having been damaged in a fire in 1761.

Ex-JPL conceptual artist Kurt Wenner created this anamorphic drawing in 2010 for Greenpeace, to commemorate a million-signature petition opposing genetically modified crops in Europe.

Seen from this angle the illusion is so compelling that it’s hard to tell what’s what. Within the circle Wenner (addressing reporters) is real, as are the five people behind him bearing signs, and the bales immediately surrounding them. But I believe everything else within the ring is drawn. For comparison here’s an image by Pyramid Visuals, which produced the substrate on which the image was printed.

At 22 meters square, the image set a world record at the time as the largest of its kind drawn by a single person.

Simon Beck creates large-scale artworks by walking through fields of snow. Working primarily in the Alps, he creates about 30 drawings each winter, shuffling through pristine snowfalls guided by a compass. A single image can require 10 hours’ time and 30 miles of of walking.

“Making these drawings is map-making in reverse,” he told the Guardian. “You start with the map, and you need to make the ground agree with the map.”

Another reversible face, this one by British artist Rex Whistler (1905–1944).

The approach to Macon, Georgia’s 2012 International Cherry Blossom Festival was much safer than it appeared.

Artist Tracy Lee Stum’s anamorphic sidewalk painting took two days to create.
