Ever wondered how google would look like if it was on terminal mode (a la *Nix shell)? Then checkout Goosh! Goosh is a project that Stefhan Grothkopp started. The application behaves similar to a unix-shell wherein you type commands and it returns results based on your request (which in this case is web search results). I personally love the idea and have been using the tool since i found it.
This reminds me of the days when terminals were hip and cool. I do wish that the background was black though and the fonts converted to green to give more terminal-like feel to it but either way its two thumbs up for me ;)
