Programmable search engine: Yubnub

This is seriously cool: Yubnub
It's like a command line that you can send commands to that perform all sorts of operations such as:

• gim "metallica" - google image search for metallica pictures
• ls - show all available commands
• man xyz - show man page for command xyz

and one that is really fun is tts --voice=charles "hello sir, can i have a pale ale?"

The cool bit is anyone can make their own command and add it to the system so things like this have been added:

• wikip metallica - find all wikipedia entries that mention metallica
• ASCII metallica - generate a huge range of ascii art for the word metallica
• phpfunction - return the manual page for a specific function

For a fair sized list check out the Yubnub golden eggs page.
