Words cannot express how much I love this redesign of the Moscow Metro diagram. And this is the real thing, not a self-made project like my humble little offerings. It’s clean, stylish, informational and gorgeous. The repetition of the famous Circle Line at interchange stations is particularly nice.
Do yourself a favour and visit the design studio’s site for a closer look. The “Process” tab is especially worthwhile, as they run through the decisions that led to the final version in great detail. Also note that this took four years of work to get to this stage!
