The Demoscene, as it currently stands
Remember those whacky demo groups back in the late 80s-early 90s? If not, they basically wrote art pieces for the computing systems they had at hand (Amiga, Mac, Win95 etc.).
Write art? That’s a weird choice of words! But yes, they basically code as efficiently as they can, to create audio-visual demos in the tiniest space possible.
I’ll leave it up to you to read more about it, but yours truly is mainly interested in the 64k category. That is, the entries have to be within 64 kiB. This includes the video engine, the audio engine, the audio score, shaders, everything.
So, summing up, the above video is a direct capture of what a 64 kiB binary does. No hidden libraries (well, except for standard ones that are on your machine already). To put it in a neat perspective, that latest Mortal Kombat game comes at a whopping 60 GiB, and it’s basically a 2D game with mostly non-pre-rendered cutscenes.

Not necessarily gaming-related, but certainly artsy!
