I love Pixel Art, I have 3 posters decorating the walls in my apartment with pixel art, probably because I grew up playing those 8/16 bits video-games for consoles like NES, SNES, Master System and Genesis. One of the masters of this trade is the EbOY.
EbOY is Kai Vermehr, Steffen Sauerteig and Svend Smital. We create re-usable pixel objects and take them to build complex and extensible artwork. And we make toys.
Some of their clients include big names such as: Adidas, Adobe, Amazon, Arena Magazine, Attenda, AXE, Bizz Magazine, Blender Magazine, Boston Magazine, Brazen, Bungalow Records, Carraro, Coca-Cola, Computer Arts Magazine, Create Online Magazine, Creative Review Magazine, DaimlerChrysler, Der Spiegel, Design Plex, Diesel, DKNY, Edge Mag, Egg, Electronic Gaming Magazine. and many more.
The basic idea which led to to eBoy was to embrace the new opportunities... the decision to work directly on and for the scree let to the use of pixels as the only unity of representation. This is how they began work based on a modular system which evolved into works of complex richness.
