Chris this is so cool! Earlier this year I was thinking about doing the same thing, mostly for making interactive CLI tutorials - similar to the Git tutorial you have in the examples. Then I tried with Jupyther notebooks, but it feels quite limited, and they are not as easy to work with as Markdown files.

I followed the installation instructions and it works super well! [The Gifs in the README already look promising, but it still lacks the empowered feeling you have when interacting with it.] There seem to be some rough edges, e.g. I bricked my session when enabling Docker probably because Docker wasn't available, but overall it all works super well.

Some small things w.r.t. presenting the project/idea: - I nearly clicked away because there was no quick demo, merely pictures. In part because I scrolled over the install instructions - which could be fixed by a table of contents, but also because cloning and installing is quite a barrier when you still haven't seen much from the product. - The website of ottomatica have some buttons which don't seem to do anything.

Anyhow, out of curiosity, what are your plans with it? I noticed it was an academic endeavor, are you planning on commercializing it and/or building a company around it?
