This is a project by Marcin Ignac entitled "City Icon" from 2012. It's a generative city simulation with a variety of randomly created systems. Their interactions create a dynamic and constantly changing view of an imaginary city. I like the balance between the order of a city and the randomness in the direction that its parts take. How the water flows through and energy sources appear is fairly random, but what's impressive is that it is still is identifiable as a city, like you might see from an airplane above when flying at night. The generation transforms when it becomes a series of cells that make up a living organism or a collection of energy sources. I imagine there was quite a bit of pseudo-random number generation involved in making this project, as its parts seem to relate in a nice way.
