THE FIRST GREATEST ILLUSION
The very first illusion is to believe that there is one, unique world of perception. The mind and the world we experience are inseparable, as it is the mind that makes the world meaningful. Our mind IS our world. Despite the fact that our mental construct of what is perceived is distinct from the objective reality, our mind accepts it as real.
Every organism, man as well as animal, lives in its own subjective spatiotemporal world that semiotic philosophers call ‘Umwelt’ (from the German Umwelt, ‘surrounding world’, or ‘life-world’). According to the biologist Jakob J. von Uexküll, organisms and their life-world shape each other in a functional loop (see fig. below): interactions between the subject and the outer world, mediated through the sense and effect organs, determine the world framework of the subject. Thus, a particular stimulus which has a perceptive cue or meaning to the subject induces always a purposeful reaction.

Early Projector
This Roman artifact is thought to be the forerunner of the magic lantern. In fact, by placing the flame of a candle (or a lantern) behind the elliptic lens, it was possible, according to Flavius Russus, to cast on a white wall the image/portrait painted on the lens, like the same principle as modern slide projectors.

Reuleaux-triangle intermittent mechanisms
The Reuleaux triangle is a convex triangle-like shape, each side of which is an arc centered on the opposite vertex. Any curve of constant width can form a rotor within a square, a shape that can perform a complete rotation while staying within the square and at all times touching all four sides of the square.
Intermittent motion mechanisms were first used in sewing machines, nowadays they are used in many mechanical applications to index film in cameras, projectors, and in film processing equipment…
