That was an extremely interesting article. Many of the examples are also quite stunningly beautiful. I guess making games is in a sense already a way to visualize data/code, though in a more roundabout way. I don’t have any links to something exactly like what you are describing, but some of the software for generating fractals is somewhat similar. You can create beautiful, infinite patterns by inputting rather simple mathematical formulas, though there the goal is more aesthetic than educational.
