Udayakumar Rayala on our forums has crafted a greasemonkey script that will post desktop notifications when new results are available from search.twitter.com. BrowserPlus+greasemonkey (+Udayakumar's creativity) makes search.twitter.com more usable.
I personally love this hack as I'm a huge user of search.twitter.com, I leave a tab or two open all day long monitoring some topics I care about, but I'm not particularly interested in installing native applications to get more instant updates on the twitter-o-sphere. So this hack has made my life better. Thanks Udayakumar!
