Vivisimo, a provider of search software has marked the second birthday of its consumer search site Clusty.com with a redesign and new features, including a font size selector, a "more" tab, and the ability to search within results. Clusty.com now features a "Labs" page that hosts new search applications developed by Vivisimo's engineers. At the Clusty Labs page, consumers can try out Clusty Cloud, a customizable visualization tool that lets users see an immediate overview of any topic on the web, and do specialized searches of a Benjamin Franklin portal or of Shakespeare's plays and sonnets. The company plans to use the Labs page as a testing ground for improvements in the overall search experience for its end users. New technologies developed and tested in the labs will also shape future versions of Velocity, the company's enterprise search platform.
