Based on the work in the Fuerte SIG "ROS GUI" i want to announce the availability of two new stacks:
* "rqt" includes a set of ROS specific UI plugins (written in Python or C++) providing features like:

** Viewing images and videos
** Introspecting arbitrary topics
** Sending arbitrary messages and service requests
** ... and several more ...
** 2D plotting of numeric data
** Visualization of 3D poses
** Visualize the ROS computation graph as well as package dependencies

* "qt_gui_core" provides the Qt-based infrastructure for rqt

Both stacks are available for Fuerte.
For more information please take a look to the (to be extended) Wiki pages: http://ros.org/wiki/rqt

Please take a look and give it a try.
I hope the available tools are helpful to a lot of people.

Cheers,
- Dirk
