Having always been fascinated intersection of light and colour, I decided to explore how a combination of colours could create motion in a still image. For my Science of Light final project, I studied the science behind illusory motion over five weeks and recreated a few Rotating Snakes illusions: a type of illusion characterised by a circular motion of concentric circles. Through my research, I was able to investigate that illusory motion is the result of shortcuts used by the brain during visual processing. Even though the brain processes information in one-tenth of a second, it is still 100 milliseconds behind the real world. Therefore, a lot of its processing is based on predictions based on past experiences which lead to the perception of motion. This extended project helped me develop skills in inquiry and synthesis using different sources from multiple classes. Theories about the centre-surround system, peripheral drift and edge detection helped me understand the importance of colour, value and luminance in creating optical illusions. Since colours of contrasting luminances promoted motion I created a luminance gradient using specific colours based on calculations. High contrast shapes and repetitive patterns increased this perception leading to my creation.
