Monitter is a real time twitter tracker that lets me follow three keywords simultaneously. It’s like Tweetdeck mixed with Summize (excuse me, Twitter search), although the creator states that is was inspired by Tweetdeck and popurls.
The background, which admittedly is hard on my eyes but looks so cool, can be changed to a light theme. The info panel at the top of the page (not shown in my screenshot) can be hidden in order to have more space for results.
Monitter also includes a widget that will include search results on a website. Below is an example of the Monitter widget that uses my own page style and is only searching on one term; bigfoot.
