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.
This entire animation is contained in a 64 kilobyte EXE file. Everything you see and hear is constrained to 64k!
You can run it on your own computer!
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.
