Hi all.
I have created a bootstrap helper package to create tiny Pharo images. I use this for CodeParadise, but it can also be used to create tiny images which run outside the browser. It can create both 32 and 64 bit images. A tiny image is around 200 to 300Kb.
Two example usages are present. See the README in the repo.

Happy 2023 and happy Smalltalking!
