4 example scripts of ~30 lines each that should be easy to mix and match on a phone or tablet.

A voice recorder you can tweak the source code for, right on your Android phone
One little detail here involves Android permissions. I almost ended up asking for microphone permissions in Lua Carousel. Luckily I managed to stop and ask myself what the user experience is. "Hi, I'm Lua Carousel, could I please have access to your mic?" Ick! It seems like a bad idea to ask for a permission for the whole app just in case some single script uses it. Probably affects the conversions from this particular blog post, but I don't want to feel like I'm contributing to the general fatigue over apps asking for permissions. :shrug:

One nice reusable abstraction my LÖVE apps have all converged on is an immediate-mode button primitive. I draw all my buttons each frame along with all the callbacks they need, and a couple of framework-y lines of code in the mouse-press callback is all it takes to get them working. Last night I realized (while poking around in the LÖVE forums) that my hacky sliders in Lua Carousel's settings admit a similar abstraction (even better than the one there). The only additional complexity is it needs a couple more lines in the update callback that continually refresh the backing value as you drag the slider.

Conway's game of life with colors
I think I'm going to call this variant "ChromaCline"

The Game of Life is one of my favorite programs, but I've never tried to go deep in learning about it, and as a result I still learn fairly obvious (with hindsight) things about it. This time I realized two things:
- I don't need to keep checking if a cell is in bounds. Just don't update a border of cells!
- I don't need to clean up the new array at each time step! :facepalm:

Yesterday I turned a couple of my unused kids apps into just scripts you could run on Lua Carousel.
spell-cards.love (exercising my phone's microphone for the first time)
Both qualified successes. I didn't uncover any bugs, but the programs were 250 and 350 lines long, which starts to feel too long for my implementation of scrollbars.

Huh, I just realized I've been doing #DecemberAdventure all along and just hadn't thought about it like that.

This bug I foisted on myself today was a real "things are not as they appear" puzzle.
bugfix: only check for settings menu when open

I fixed several embarrassing bugs in Lua Carousel in the past week, including:
- Buttons now flash to give you feedback that, e.g. the file was actually saved like you asked and you didn't fat-finger the wrong button.
- Tapping didn't always move the cursor.
- If you selected some text and hit 'clear', the app would crash.
- Dragging on empty space above the settings menu selected text beneath.
- Lots of jitteriness.
