  1. I implemented Bresenham's line algorithm for my ZX81 "game" (more of a demo of routines at the moment). I use it to draw the chunky grey line crossing diagonally. It's quite a fun algorithm, and apparently the second time that i have implemented it: there is a version in BASIC in Chapter 18 of the ZX81 BASIC Programming manual that i surely typed in as a child.

  2. This year I didn't enter @logiker 's Vintage Computing Christmas Challenge 2024 (#vccc2024), but after watching the results on his YouTube channel (youtube.com/watch?v=kJYbIC-14s), I couldn't help but to get out the #ZX81 and write some basic code. 🤓
