This article was such a cool trip down memory lane, and as an old-timer that hasn’t looked at this stuff since the early 90s (mode13h anyone?) I am so happy to see how strong the scene is today.

His live set demo is pretty neat

Just to clarify for readers who didn't read the interview, not a live set, it’s a 64kb demo that looks and feels like a recording of a livecoding competition. So “live set demo” is technically correct because it’s a “live set” themed demo. But it’s not actually a live set :-)

Mode 13H was pretty nice. But mode 13X, hacked to have square pixels, was the coolest!

Mode X allowed pretty cool stuff, like fake true color with interlaced lines (R,G,B), double buffering etc!

Fond memories.

Here is a YouTube rendition of a demo I implemented in 96, showing those techniques https://m.youtube.com/watch?v=t8o-uuq73UU&pp=ygUQTmlra2kgaml...

I really enjoyed the interview, and I definitely resonate with the art being free from so called “value” as an asset, truly a pure from of artistic creation and expression. I am curious to know more about the scene and it sounds like they would be welcoming to n00bs, you guys recommend any upcoming live events to keep track of?

The biggest pure demoscene event is Revision in Saarbrücken, Germany. The 2026 edition has yet to be announced, but it is always during the Easter week-end. They have a dedicated newbie corner if you are interested https://2025.revision-party.net/about/newcomers/

Nice to see Setsukos blog here on hackernews! She has done a lot of great interviews with sceners over the years you should check out.

I met her once at Tokyo Demofest, and I still feel bad about making her try the Swedish licorice I had brought... :)

I feel like MIDI trackers are a lost art - back in the 90s instead of using mp3s, we stored music as series of instrument beats - this not only was more efficient but since beats were triggered by code, that meant it was trivial to sync visuals to it - which gave these 64k intros their unique vibe.

Warms my heart when they mention his 'discography' and it's a link to pouet.net, one of the various scene.org sites been around forever and still going. Having any kind of documentation/archives of a subculture's history, especially from around that time when digital things just disappear, is great to see.

I always found Demoscene to be a curious phenomena. A combination of fascination and not understanding the point.

Seems to be mostly a European thing, too.

They're talented hobbyists who are not interested in monetizing their passion. Such people exist in US too, although perhaps are more rare.
