Unofficial Google Shell
Goosh.org is a Google interface that behaves similar to a UNIX shell. You type commands and the results are shown on the page.
will list all of the working commands. For instance, I can:
video linux journal
to get search results that feature all LinuxJournal.com videos or
wiki linus torvalds
to get all Wikipedia search results matching Linus Torvalds.
Ultimately I don't know how useful this actually is, but it is kind of fun. :)
