Before anything, you need to know that what you are about to see are renderings! Probably some of the more refined and advanced 3D rendering I ever seen. Also known as Architecture visualization, these works of art where created by Israel based Studio Aiko. Founded by Yair Alony and Meny Hilsenrad in 2005, Studio Aiko is a young & dynamic studio, specializing in a wide variety of CG content and visual effects. They provide high-end products, aimed for excellence, while constantly renewing and refining their skills. It is pretty hard to tell that these images are 3D !!
