YubNub Search Bar - works in any browser
Inspired by Felipe Gomes' Google Command Line, Sean O'Hagan has written a neat YubNub search-bar that lives at the bottom of your browser. The neat thing about it is that it works in almost any browser, because it uses a simple HTML frame. To start it up, simply type cmdline into YubNub. Then try typing "gim porsche" into the command-line at the bottom of the screen (or a URL like google.com).
