An intuitive molecular editor and visualization tool
Avogadro is an advanced molecular editor designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science and related areas. It offers a flexible rendering framework and a powerful plugin architecture.
PLplot is a cross-platform, scientific graphics plotting library that supports math symbols and human languages (via UTF-8 user input strings); plot capabilities for multiple non-interactive plot file formats and in multiple interactive environments; and bindings for multiple computer languages.
A free cross-platform library of fast C++ routines for the plotting of up to 3-ranged data. It can export to bitmap and vector EPS/SVG files. There are window interfaces (GLUT/FLTK/Qt) and console tools. MathGL can be used from C/Fortran/Python/Octav/Lua
Hypercube is a tool for visualizing DOT (graphviz), GML, GraphML, GXL and simple text-based graph representations as SVG and EPS images.
Hypercube comes with a Qt based GUI application and a Qt-independent command-line tool. It uses a simulated annealing algorithm to lay out the graph, that can be easily parameterized to achieve the desired look.
The main development goals are portability and easy usage rather than high performance and complexity.

RLPlot is a scientific plotting program to produce high quality graphs from data. It is a cross platform development written in C/C++ and may be compiled under Windows32 or Linux. RLPlot for Linux uses Trolltech's Qt.
QuteScoop is a platform-independent status indicator for VATSIM. It's available for Windows, Mac and Linux.
Visit its new development location https://github.com/qutescoop/qutescoop for current downloads and source code.
FractalNow provides users with tools to generate pictures of various types of fractals quickly and easily.
It is made of both a command line tool, FractalNow, and a graphical tool, QFractalNow.
The graphical tool, based on Qt library, allows users to explore fractals intuitively and generate pictures.
Both tools are entirely multi-threaded and implement advanced algorithms and heuristics that make computation very fast compared to most existing free fractal generators.
The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types, such as logic analyzers, MSOs, oscilloscopes, multimeters, LCR meters, sound level meters, thermometers, anemometers, light meters, dataloggers, function generators, power supplies, GPIB interfaces, and more.
CCVisualizer is a multiplatform Closed Caption or Subtitle visualizer for movies or films (es Youtube, Megavideo). By downloading the movie's SRT file, it is possible to visualize it, to pause and to manually align video and text.
Gnupylot is a GUI for gnuplot (the widely used multi-OS plotting utility). It's written in Python using PyQt4 libraries. With Gnupylot you can save your plots (even the datasets). It's still in Alpha stage.
Preparation of GPS routes and analysis of GPS logs in the context of outdoor sports (biking, skiing, trecking, gliding, geocaching, mountaineering). Our hope is to have a multi platform, multi GPS file and map format software.
A cross-platform cellular automaton facility. Implements simulation and visualization of multi-dimensional cellural automatas locally or in distributed mode.
MicroArray Genome Imaging and Clustering Tool (MAGIC tool) is a platform-independant java program for analyzing MicroArray data (.tiff scans & .txt godlists) via graphs and clustering operations (including QT-clustering). http://www.bio.davidson.edu/magic
OpStation_Qt: Operator Station for controlling multiple robots/robotics/devices using Player/Stage/Gazebo written using the open Qt GUI libraries. Written in C and C++. A good platform for storing data from scientific experiments as well as recreation
The Grace ASCII Import Wizard ("gaiw") is a cross-platform, Qt-based GUI allowing Grace (http://plasma-gate.weizmann.ac.il/Grace/) users to create 2D XY plots from ASCII data files very easily.
