See and touch “impossible objects,” which change their appearances drastically in a mirror, and learn the principles of illusions for two special types: the “left-right reversal illusion,” in which the object facing toward the right turns to the left in a mirror, and the “translation illusion,” in which the object facing toward the mirror translates into the mirror instead of turning around. Once you understand the principles, you will be able to create your original illusion objects by paper crafting and origami folding. Also, you might learn the power of “seeing”, which is one of the most basic functions to live.
