This is an experimental, partial, compact rebuild of some ideas of https://jupyter.org/%|%Jupyter Notebook%|% which first was presented at EuroTcl 2019.
The name is derived from Taygete (Ταϋγέτη) which is a small retrograde irregular satellite of Jupiter, aka Jupiter 
XX.

It consists of a webview (the rendering component/library of a web browser) with an added Tcl interface, plus some Tcl and JavaScript to provide a user interface resembling Jupyter Notebook. The webview part is basically taken from the https://github.com/zserge/webview%|%Tiny cross-platform webview library for C/C++/Golang%|% with the Python interface taken as starting point for the Tcl interface.

No browser and webserver are required so it can be made into one binary with zero installation and without requiring network infrastructure.

The Tcl binding is about 650 LOC and can be found in the https://www.androwish.org/home/dir?name=undroid/twv%|%undroid/twv%|% folder on AndroWish's website.

The UI/engine is a single Tcl script of about 1300 LOC and can be found with some examples in the https://www.androwish.org/home/dir?name=undroid/tsb%|%undroid/tsb%|% folder on AndroWish's website.

A ready made ZIP kit for immediate experimation is available in http://www.ch-werner.de/AndroWish/TSB.kit%|%TSB.kit%|%. It supports the three major desktop platforms Windows (32 and 64 bit), MacOS (Intel, 64 bit), Linux (Intel, 32 and 64 bit, distro agnostic but a decent version with gnome 3 runtime is required). If started without further arguments, it presents an overview page with links to examples.
