Viana.NET 6.6.1, published by Dr. Adrian Voßkühler, is an open-source educational application designed to teach physics through real-time motion and color analysis. Falling under the Science / Physics category, the program acquires live webcam streams or pre-recorded video files and automatically tracks colored, moving objects, then translates the resulting trajectories into measurable physical quantities such as position, velocity and acceleration. Teachers use it to demonstrate conservation laws, harmonic oscillation or projectile motion without specialized lab hardware, while students can repeat experiments at home to verify theoretical predictions. Researchers value its ability to export raw data to CSV for further statistical work, and hobbyists employ it to calibrate motion-control systems or analyze sports technique. The project has released two major versions to date: the current 6.6.1 build, which refines color-threshold algorithms and adds support for high-definition cameras, and the earlier 2.x branch that remains compatible with legacy Windows XP setups. Both editions provide an intuitive workflow that guides users from camera calibration through measurement to graphical evaluation, yet remain sufficiently configurable for advanced scenarios such as multi-object tracking or custom coordinate scaling. Because the entire toolchain is contained in a single portable executable, classrooms can run Viana.NET from a USB stick without installation rights, making it a practical choice for schools with restrictive IT policies. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
