Romans created 3D mosaics for their dwellings, Greeks used perspective to create gorgeous pantheons, and if you look closely, at least one Paleolithic carving appears to be two separate creatures. Color, contrast, shape, size, light, pattern, and perspective are all used in optical illusions to make your brain go crazy.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"208\" height=\"242\" src=\"https:\/\/2022.robocupjunior.eu\/rcj\/wp-content\/uploads\/2022\/03\/optical2.png\" alt=\"\" class=\"wp-image-341\"\/><\/figure>\n\n\n\n<p>Between your eyes and your brain, a lot can be lost in translation. It&#8217;s true that the two systems, for the most part, work well together. Your eyes take in a mishmash of pictures, darting from side to side almost imperceptibly, and your brain puts them in context, fitting the puzzle together into something that makes sense. Sometimes your eyes communicate perplexing sights, and your brain, in attempting to decipher them, completely misinterprets the signals.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-medium is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/2022.robocupjunior.eu\/rcj\/wp-content\/uploads\/2022\/03\/optical3-300x300.png\" alt=\"\" class=\"wp-image-342\" width=\"331\" height=\"331\" srcset=\"https:\/\/2022.robocupjunior.eu\/rcj\/wp-content\/uploads\/2022\/03\/optical3-300x300.png 300w, https:\/\/2022.robocupjunior.eu\/rcj\/wp-content\/uploads\/2022\/03\/optical3-150x150.png 150w, https:\/\/2022.robocupjunior.eu\/rcj\/wp-content\/uploads\/2022\/03\/optical3.png 763w\" sizes=\"auto, (max-width: 331px) 100vw, 331px\" \/><\/figure>\n\n\n\n<p>Patterns are a common stumbling block for people. Another mind-bender is colour context: the same colour can appear radically different when viewed against varied backgrounds. Do you recall the internet-famous dress?
