Infinite Mac can now be embedded into any website: https://infinitemac.org/embed
For a demonstration of what this can enable, see @mwicharyMarcin Wichary's amazing "Frame of preference" article: https://aresluna.org/frame-of-preference/
And for a behind the scenes look, there's a blog post: https://blog.persistent.info/2025/07/infinite-mac-embedding.html (spoiler: Marcin was the instigator for all this, conducted over a months-long 100+ message email thread).
