Just saw this new open source variant on the python notebook concept (and an alternative to Jupyter notebooks) that might be useful with Slicer:

> **[marimo | a next-generation Python notebook](https://marimo.io/)**
>
> Explore data and build apps seamlessly with marimo, a next-generation Python notebook.

Some of the differences from Jupyter:

- Fully reactive: change a variable value and all cells using that value will update. Observablehq uses this reactive model and it works quite well.
- Notebook format is python code, not JSON, so notebooks are more git friendly and reusable.
