A concept/illutsration done for the "Worlds of Android" IP book for Netrunner. The main tower here is one of the giant arcologies for the rich in this city (Notice the enormous glass-bottomed pool at its roof!) Also known as New Angeles, it has become a world capital due in part to the fact that it contains an equatorial space elevator.
The one that was actually published had different colors (more purples) but I prefer this version.
