Piet: Programming language in which programs look like abstract paintings (2002)
Introduction Piet is a programming language in which programs look like abstract paintings. The language is named after Piet Mondrian, who pioneered the field of geometric abstract art.
Over the years I have tended to field questions about the spec with "whatever you think makes the most sense", rather than any definitive clarification - thus the slightly different versions out there. The interpreter now begins sliding from its current white codel, in the new direction of the DP, until it either enters a coloured block or encounters another restriction. Note on the mod command: In the original specification of Piet the result of a modulo operation with a negative dividend (the second top value popped off the stack) was not explicitly defined.
