Here are some examples of my anim_framework ([GitLab](https://gitlab.com/ldo/anim_framework), [GitHub](https://github.com/ldo/anim_framework)) Python library in action. They all work by generating the frames as sequentially-numbered PNG files into a subdirectory called “frames”. Use the “run” wrapper script to run them; this will take care of (re)creating this subdirectory, and ensuring it does not contain any leftover output from a previous script run. It will also play back the result, using ffplay. For example: ./run readme_example to run the “readme_example” script and automatically play the generated animation afterwards. Note that the demos can take up to a minute or two to generate the frames. Lawrence D'Oliveiro <ldo@geek-central.gen.nz> 2017 April 7
