Fantastic idea. On the image format part, PPM is indeed a great way to get off the ground. If you really want something more portable like PNG then it happens to be quite a fun library to implement. I encourage you to write your own. It’s basically: - some magic number bytes - a static header to announce the image is 8bit RGB zlib-compressed unfiltered non-interlaced - a final set of magic bytes to say “here’s the actual image” - zlib compressed rows of RGB bytes, with a 0 at the start of each row So really just a fancy image.ppm.gz. What’s cool is that with 10 more lines of code you can implement animated PNG.
