Some details: based on [1], it allows to play with the quines (via mouse interactions) and understand how these work, visually.<p>Not part of my current project, but it responds to a demand I had for years. My contribution was to use the script with examples, old and new. Is so nice and interactive that now I wish for a game.<p>[1] <a href="https://github.com/ishanpm/chemlambda-editor" rel="nofollow">https://github.com/ishanpm/chemlambda-editor</a>
