We are excited to announce that anyone on the web can freely use many NCLab’s apps without creating a user account or having to log in. Available are Karel the Robot, Turtle Tina, Python, 3D Modeling, GNU Octave, LaTeX, 3D Molecule Sketcher and Finite Element Analysis. Click on the screenshot below to get to the Playground. For some functionality, login is still required – such as saving files in your NCLab account and publishing them on the web. Each app comes with a tutorial video.
