Queryster is a new Friendster rip off design for a meta search which allows you to search any one of about a dozen top search engines at any time. They include a graphic overlay which makes it simple to easily view the search results from one search engine to the next.

Search engine toolbars such as Groowe and UltraBar both make this same function easy without cluttering the page element itself. Of course this is a neat tool if you do not want to download anything.
