I really need to talk about Demoscene more. I'm not much of a creator, but I love Demoparties and Compos.
Starting a thread about my two favorite categories: 4k and 64k.
These are computer programs that are restricted to a maximum file size (in kilobytes!), but must also remain graphically impressive.
Let's start with a crowd pleaser: the timeless by Mercury.
Mandatory reading on this one: https://datunnel.blogspot.com/2014/04/the-story-of-urs.html
And now let's watch something 16x smaller. A 4 kilobyte demo: The vanishing of Ashlar by NuSan
Shamelessly plugging my own site now, where you can generate 50-video YouTube playlists of Demoscene content, sorted by type, including 4k and 64k: https://www.prods.page/
I'll keep updating this thread in the future with more of my favorites. Might start a separate Wild thread too.
This is the Vranas instance.
