K is a general-purpose vector-oriented programming language with a concise syntax. See https://en.wikipedia.org/wiki/K_(programming_language) https://en.wikipedia.org/wiki/K_(programming_language). Special-K is a subset of the k6 dialect of this language, in part due to the constrants of GLSL, which retains its concise nature and which should be intelligible and convenient for those who already know K. For those who do not yet know K, it may still be a pleasant way to experiment with fragment shaders.
