For screen-based graphic designers, working with pixels is nothing new - these tiny dots are the building blocks of bitmap graphics, one of the two fundamental types of graphic file. Digital images are made up of thousands of individual pixels which the eye blends together to give a smooth, coherent picture. Designers have begun to experiment with pixels, using them to create a graphic style that looks deliberately blocky and pixellated. Some designers strive to use as few pixels as possible to create recognizable characters and scenes; others, notably the German-based pioneers of pixel art, eBoy, use millions of pixels to build up highly detailed representations of environments. "Pixel World" collects together the pixel graphics of 30 designers and illustrators from around the world. It covers a wide variety of styles and subject matter, from pixel environments to pixel fonts, and from girls to outer space.
