Demoing Cinch, a great windows management app for OSX Lion or Snow Leopard.
It lets you resize your windows by dragging them to sides of the screen, which is really handy if you have a bunch of windows open and only want to focus on 1 or 2 of them.
Available on apple app store for a dollar today (1/12/2012): :http://itunes.apple.com/app/id412529613?ls=1&mt=12
