LCD output with #arduino and #uxn!!

Communication with the display happens on the UXN side, i ported a LCD library to UXNSMAL using only Wire.h arduino library.

When i started writing #uxn I always thought only having 4 colours was going to be a serious limitation, but with a careful colour palette and some creativity I have always been just fine with only 4 colours.

Here is the celeste spritesheet in uxn form ^__^ (There is no easy way to extract assets from a Pico-8 game so I had to redraw them all)

Catlang programming language idea: Rejoice

It's like Joy, but instead of a stack, it's a multiset, and transformations are local rewriting rules.

The program state is a bag of unordered things, transformations are represented as fractions where the denominator indicates things to remove from the bag, and the numerator, things to add. Evaluation consists of applying fractions from left to right, each to exhaustion, until the bag stabilizes.

i& recently recalled an idea i& had some time ago, for a tiny datastore in #uxn (good for savegames, high scores, etc.), and spent the last couple of days putting it together

very happy to report the result: 256 bytes of persistent storage, each byte accessible with a 2-byte key (like "a0" or "k3"), in just over 100 bytes of Uxntal! see for yourself: https://git.sr.ht/~sporeball/utilities
