Mathematicians used a technique called 'domain colouring' to transform a complex math function into this funky illustration. Abandoning long strings of digits, the researchers visualised the function by assigning every complex number in the equation to a specific colour. The brighter the shade, the higher the number (white regions, for example, represent numbers that approach infinity). The visualisation won an honourable mention in the illustration category.
