Hi all, I would like to announce a new ROS repository: http://code.google.com/p/rxdeveloper-ros-pkg/ It contains one package with some useful example files and a graphical tool for creating and editing launch files. You can easily compose computation graphs with a few mouse clicks, connect ROS nodes, run, test and change them. For more details including more pictures and a tutorial video please also visit http://code.google.com/p/rxdeveloper-ros-pkg/wiki/Tutorial Thanks for your attention. Filip Muellers
