This looks like the classic fire effect: generate rising flames by averaging pixels below each output pixel, and randomize the last row.

I remember this effect because there was a competition[1] where every entry was a fire effect in 256 bytes, and I was amazed at the simplicity of the core algorithm.

Just in time I received my brand new Commodore 64 Ultimate directly before Christmas. What a lovely made piece of retro hardware.

This is very nice, enjoyment-driven, seasonal hacking. Cool.

Brought back happy memories of the much simpler, much less impressive falling snowflakes animation, complete with Silent Night soundtrack, that I laboriously wrote in Basic on my Vic-20 one Christmas back in the 80s.

A mechanical keyboard in c64 design would be lovely.

Why would you put pics with less colors in them than c64 ? They are not even small?! (yes I now I can waste time to click one to see proper one)

Spoiler: nah, he just coded a fire effect on his c64.

There was apparently a demo party a while back where a Tiki 100 actually caught fire.

i thought this was going to involve capacitor plague. rather a retro dive into coding an 8bit digital fireplace.

Didn't need the click-bait title. I would have read it regardless (and did). I wish there had been a PRG or D64 included for the non-programmers. Fun read!

Made me think of the IT Crowd screensaver:

This is particularly awesome cause I can't imagine anyone thinking of making a fake fireplace with a computer screen in the c64 era.

That should have been a real CRT monitor to give this picture a true feeling of the 80s!
