At first glance, street artist Julian Beever's sidewalk creations look like unfinished chalk drawings of oddly morphed animals or landscapes. But if you happen upon the one perfect angle, the image magically snaps into shape, showing you a giant charging snail or an aerial view of Times Square.
The process is called anamorphosis, which involves drawing a distorted image which gives the impression of a three-dimensional scene from a certain vantage point. According to NPR, the talented artist sets up a camera or a viewfinder in the specific spot he intends his viewers to stand and draws his killer whales and beachy snapshots from that perspective. So if a passerby views the work from that same perspective, the drawings jump to life in their three-dimensional glory. But if they stand from any other position, the chalk creation appears to be elongated fragments of an incomplete design.

French street art duo TSF Crew create logic-defying works of art in the run-down areas of industrial France. Combining the cheeky thrills of a well-executed optical illusion with tst makes the perfect combination.

Commuter Katherine Ware relaxes on street artist Kurt Wenner's 3D work of art as he adds the finishing touches in Waterloo Station on October 17, 2007 in London, England. Wenner is famous for combining traditional street painting with classical training, illusion and performance to invent an art form of his own know as anamorphic, illusionistic or 3D painting.

Kurt Wenner, 3D chalk master, recently created a less perilous way to climb on the Grand Canyon with his massive optical illusion. Located at the South Rim of the park, the installation looks 3D from certain points of view thanks to 150 hours of hard work on Wenner's part. While it may not measure up to the real Grand Canyon experience, the photo ops may come out victorious.
Dutch artist Leon Keer is known for his impressive street art displays that play with perspective, but he also knows how to attract onlookers -- by choosing a recognizable theme. One of his most recent works seen in the Netherlands paid homage to Pac-Man, the 1980s arcade game.

Artist Qi Xinghua created this work of art entitled "Macao's One Impression" outside a local shopping center in Macao. Hidden within the 120 meter-long optical illusion are all of the city's historical and architectural landmarks.
A Flickr user photographed this impossible object on a building facade. The rectangle uses overlap and various perspective angles to create the illusion of the twisted shaped.
When Kelly saw the cover art for her 'All I Ever Wanted' CD, she didn't recognize herself! "It’s very colorful and they have definitely Photoshopped the crap out of me but I don’t care. haha! Whoever she is, she looks great,” Clarkson wrote on her blog at the time.
Jennifer Hudson had much fuller figure back when she released her first solo CD. But in a recent interview with Dateline, Hudson recalls feeling shocked when she glimpsed her body on the album's cover. "It was like, 'Where is the rest of me?' They photoshopped me probably to the size I'm now on that cover, but we all know I was nowhere near that. Why would you Photoshop that?"
Take a closer look at Adam's debut CD cover. Notice anything missing? Yeah, that would be his left shoulder!
Madonna's a huge fan of photoshop - this much we know. The 53-year-old singer typically uses the image altering program to smooth out her wrinkles -- as she did on this album cover. But can we talk about the odd proportions of her body? The torso-to-arm ratio is just off ... in fact, Madge's pose looks downright painful!
Britney Spears was dealing with one of the darkest times in her life when 'Circus' hit stores. The star had put on considerable weight and was dealing with various mental problems that altered her physical and emotional well being. However, looking at the album art, you could never tell! The photo is so altered it looks less like a pic and more like a painting!
We love Mariah's luscious curves. Too bad whoever Photoshopped the cover of her album 'Memoirs of an Imperfect Angel,' isn't a fan. Just check out what they did to her waist in the middle shot -- it's not human!
In real life, nothing much about Heidi Montag's body is real, so why should her album artwork be any different?! However, the artist who retouched 'Sex Ed' went a little overboard when working on Heidi's face. The reality star's eyes were moved so close together she looks a bit, well, cross-eyed.
Around the time Jessica released her 2010 holiday album, the singer had begun to take some heat for her expanding curves. Perhaps that's why whoever Photoshopped the CD cover blew out the brightness, thus hiding her rounder face and part of her body!
