Tumblsaurus is a web application that allows to browse tumblr in a semantic-associative way. Given a keyword, it will look up four related words (synonims or words used in the same context) and display the latest tumblr image results for that topic. It is possible to browse the results by clicking on the images or typing another keyword.
