How can you go from a word like 'morbid' to a word like 'ecstatic'? Or from 'fastidious' to 'vigil'?

Synonymy is a game of finding the paths between random words through their network of synonyms. By taking the synonym of a word, and then a synonym of that synonym, and so on, you can ultimately arrive at any other word in the English language. (more languages forthcoming!)

Website: http://www.gigapan.com/gigapans/159329 -- In order to compute relative distance, all synonyms were mapped using 3d graphing software, as if each word were a planet that had a gravitational pull proportional to its number of relationships to other nodes. Above is a 2D representation of that model, a 40,000 x 40,000 image.
