was quite amused with this  site I came across today:  Goosh.org is a browser based shell for Google created by Stefan Grothkopp. You can use this to search across Google’s various services like images, blog search, wiki, news and more. You can use the up and down arrow keys for previous commands and use the tab key for auto-complete (which uses google suggest).

Take Goosh out for a spin: goosh.org
