Here’s another example incorporating a back wall to the artwork. Sure he could have stretched the piece over a long space of sidewalk to play with our perception, but by creating this ad for Celebrity Cruises with a back wall, the drawing looks right no mater what angle you view it from.

Of course, he doesn’t incorporate backdrops into artworks that don’t need them. In fact, adding a background to this reflecting pool illusion might actually distract from the amazing likeness of the actors portrayed in the sidewalk.

If you need further proof that Wenner is certainly one of the masters of his craft, consider the fact that he was the first 3D chalk artist to conceive of an interactive chalk drawing as seen in this photograph from 1987.

Zip-lining across a city street can be fun, but it’s nothing compared to flying across wild terrain. For those that don’t have the time or money to get away from it all though, Wenner offers a grand compromise with this gorgeous canyon advertising the beauty of wild British Columbia.

For their front cover design (scroll further down), a photograph of the group traversing a zebra crossing, the photographer Iain Macmillan was given only ten minutes to take the photo whilst he stood on a step-ladder and a policeman held up the traffic. In the scene, the group walk across the street in single file from left to right, with Lennon leading, followed by Starr, McCartney, and Harrison. McCartney is barefoot.

It might be interesting to mention how to the left of the picture (parked next to the zebra crossing) is a white Volkswagen Beetle motor-car which belonged to one of the people living in the block of flats across from the recording studio. After the album was released, the number plate (LMW 281F) was stolen repeatedly from the car. The crossing is also a very popular destination for Beatles fans and there is even a webcam featuring it!

Few more examples of Gregor Wosik’s work:

Actors pose with gym equipment on what the Guinness World Records bills as the world’s largest 3D painting, at Canary Wharf in London (November, 2011)

This record-breaking drawing was created in London’s West India Quays, Canary Wharf, but even if you were in the city at the right time, the chances you got a glimpse of it are pretty slim…despite taking seven days to put up, it was removed the day after it was finished.

Update 07/06/2011 – Thanks to our dedicated fans we’ve managed to identify the author behind this monumental achievement. His name is François Abelanet and may find more photos here.

The lead artist behind this work is Tracy Lee Stum, who happens to hold a Guinness World Record for the largest chalk painting by a single individual (as opposed to the largest chalk drawing by a group, which is featured on Moillusions here). Yeah, she’s pretty impressively talented whether working with a group, like she did on this Mouse Trap project, or working alone, like she did on the record-winning Last Supper piece below.

Qi Xinghua says he has calculated three different formulas that can be applied on all paintings of varying sizes. He also added (quoted below):

To put it in the simplest way, it’s reversed vision, which is also called inverse-perspective. From our normal vision, nearby objects are big and far away ones are small. I use the opposite method to make far away objects big and close objects small. In this way, a two-dimensional painting turns three-dimensional.

Don’t ask me why, but I have a feeling we’ll be seeing much more of this artist’s creations in the coming weeks! Even after seeing so many awesome pavement drawings, I can’t seem to perceive below pavement as a flat surface. How about you?

The artist(s) behind these models isn’t known to me, yet the work he did greatly reminds me of Josh Sommers’ CG illusions posted in 2008. Even when being aware these illusion were artificially generated, the question still remains – how was this achieved? How would the object appear if we rotated the model, and show it from different angle? Would these appear the same if they were done in real life? Please share your opinion!

At first I thought Oleg did a real-life installment of his impossible nut, but I then I realized he created it using some sort of 3D imaging software. Still very realistic, don’t you think? Have you noticed The Instructions from Hell shown in the back? This one appears truly realistic!
