FXYT is a tiny canvas colouring language with 36 simple stack-based commands. By evaluating input code for each cell of a 256×256 canvas, FXYT determines the color of each cell. Inspired by Martin Kleppe’s Tixy project, FXYT offers its own language and a larger canvas size. Users can experiment by writing their own code, with demos available. The language supports coordinates, data stack, loop control, colors, integers, arithmetic, division, comparisons, bitwise operations, and more. FXYT allows for creating visually appealing patterns and gradients. Controversially, division by zero can be handled differently in different modes. Explore the link for more information.
