Strolling through my flickr feeds I landed upon the photo below in Chris Messina's photostream. It's from an innovative little application called Todos. Todos, which means "all of them" in Spanish, displays a window showing each icon for every application on your Mac. Clicking on an application's icon launches it. Todos is essentially a glorified launcher. Oh and for those of you playing along at home, this is post number 400.
Want to know what all of these apps are? Click.
