Many keyboards use the qmk firmware these days, qmk.fm, which can be programmed with the Vial configurator, get.vial.today .

And for something more weird but still fully featured, Miryoku is a fairly common micro-keyboard layout, https://github.com/manna-harbour/miryoku https://github.com/manna-harbour/miryoku . Why? Well, I really admire Jonas Heitala's documentation of his journey to find a layout that fit his aesthetic: https://www.jonashietala.se/blog/2023/11/02/i_designed_my_own_keyboard_layout_was_it_worth_it/ https://www.jonashietala.se/blog/2023/11/02/i_designed_my_ow... . My layout isn't as extreme, it's still qwerty-ish, but I've been heavily inspired by his thorough analysis.
