Although it is a virtually created image, we guess that it serves the purpose of paradox illusions quite well and is also a bit unique in its own manner (although projects the same you have seen so many times). The figure appears to be three dimensional. But to be that stretched, it must not begin and end at the same levels. However clearly in the image, both the beginning and end of the pattern is on the same surface. Is it just us or do you also believe that the sky background behind it is adding so much depth to the final illusion effect?
