Green Waves is the latest great GIF series by Nicolas Sassoon, it is part of a collaboration with Kenzo who says; "Green Waves was inspired by the new Kenzo Spring Summer 2012 prints. Using a green and black moiré pattern, the abstract series is evocative of tropical water scenes: waterfalls cascading, movements of large bodies of water and ripples over the surface." See more;
Nicolas has started another similar Kenzo-inspired GIF series focused on a different color and landscape, they will be featured at Kenzine. I really like the first one called Red Sea.
He has also recently launched his new website where you can find several unpublished works and documentation about his past and current projects >>> http://www.nicolassassoon.com/
