Reacteur.com is now Mozbot

Mozbot is a search engine built on top of Google natural and paid search results, with a number of additional features not found on Google. For example, you’ll see query word definitions directly on result pages, links to related search terms, thumbnail results and links to archived copies of web pages. Other links let you add results to your favorites, email pages and so on. It’s an interesting approach to extending Google that will appeal to some.
