OneFinger is a general-purpose GUI for composing CLI commands with the mouse. Although entirely graphical, it does not attempt to hide the underlying CLI language. It increases your productivity over classical hand-typing by caching commands typed into terminals, which tend to be highly repetitive. Repeated commands can be selected from a list, ordered by last usage time. It includes an integrated file browser that helps you insert filenames without typing them. and allows you to see only those programs that make sense with a given file.
The Little Launcher is an application launcher. When you run it, a small window will appear, in which you can write the name of your application and some parameters to make it run. It is modeled after SlickRun (http://www.bayden.com/SlickRun), but runs on various platforms and does not stay in memory.
adesklets is an interactive Imlib2 console for the X Window System. It provides to scripted languages a clean and simple way to write great looking, mildly interactive desktop integrated graphic applets (aka "desklets"). It can also be used as a command line oriented graphics editor, a bit similar to ImageMagick, but with different functionality.
