Anamorphic Illusions are distorted projections or perspectives requiring the viewer to occupy a specific vantage point to reconstitute the image. In other words, you must be looking at the right angle for the optical illusion to work.
You may have seen these on streets around the world like this one or this one, but I’ve personally never seen an illusion quite as real as the video above. The color, shadow, and texture are all spot on. I had to pause and rewind three times to soak it in.
Here are some illustrations that demonstrate how the illusion is created:
As you saw in the video, it’s necessary to stand at the right angle or you will lose the 3D effect.
I would really like to see one of these in person some day…
