This implausible Liquib Mirage of an old train shows a double replication of the upper portion of the original picture, with the first copy inverted and the second upright.  Actually, some rare natural mirages can have multiple images, (like the Fata Morgana), but you would never see a real-world mirage quite like this scene.  For one thing, a true mirage of an object could not occur at such close range -- the light waves could not be refracted enough over so short a distance (at least not through air).  Liquib, however, can easily violate the laws of physics and is not bound by common sense perspectives.  The Mirage images were scrunched shorter than the original train by setting the Mirage Elongation parameter to -42 (a positive Elongation would cause Mirage images to be lengthened relative to the original).  The program automatically calculates the image proportions needed to accomodate the configured Images and Elongation values.  The Waviness and Intensity parameters can also be adjusted to control the scale and degree of Mirage distortions.  This stationary scene was captured after the Mirage Effect was finalized.  While a Mirage is still active, the undulating distortions would typically be in constant motion -- meandering, swirling and/or traveling.
