Elevated by RGBA and TBC
Why Hacker News recommends it
HN repeatedly holds it up as the benchmark for what procedural generation and size-coding can achieve in 4K.
What it is
Elevated is a 4 kilobyte PC demo by RGBA and TBC from Breakpoint 2009. It fly-throughs a realistic procedurally generated landscape with synthesized music and post-processing, all from a tiny executable.
Recommended by 7 HN commenters across 7 different months, 2009 to 2025.

In a different style, the "Elevated" demo, coded in 4K (you'll have a hard time believing it if you haven't seen it yet): [this video]

Check out 'Elevated' - winner of the 4k PC demo category at Breakpoint 2009. It's a fly-through of a realistic looking procedurally generated terrain model with music and some fancy post processing effects all squeezed into a <4096 bytes executable. Even my moderately high-end PC can't run it (I suspect because it shoves an overwhelmingly huge triangle mesh at the GPU) but there's a video here: [this video]

Two more by Farbrausch the.popular.demo [LINK] and Candytron (64K) [LINK] For some newer releases blunderbuss by Fairlight [LINK] is very different is style but still very cool and two post about the particle system behind the demo [LINK] [LINK] Elevated by Rgba & TBC [this video] is a great example of what people can do in 4K, and they even have a presentation about the technical details [LINK] and State of the Art by Spaceballs [LINK] is a highpoint of the amiga scene (edited to add, which I should have clicked on the link to see it had already been embedded)

Cool, but I think my favourite 4k demo is still Elevated, which is much less obviously procedural. ( [this video] )

Indeed, keep going, and you may reach this level of awesome: [this video] (Quite realistic terrain generated by a 4 kilobyte binary, along with music . Source code and its discussion here: [LINK] )

I know that a huge part of the demoscene culture is keeping your trade secrets close, but I'd love to see a YouTube playlist where authors or people with significant graphics experience do in-depth teardowns. Those of us like myself who only take a passing interest from afar are still blown away by how amazing results of demos like "elevated" from 2009 [1]. I've heard Iñigo Quílez, but I am curious if there are people interested in doing teardowns of winners moreso than elementary concepts (although of course the latter is much more applciable outside of the demo scene). 1= [this video]

It's 12 years old now, but I am still extremely impressed by this 64k intro [LINK] and also by this 4k intro [this video] :) And overall this website is extremely interesting with tutorials and code and great explanations [LINK]

For the impatient or people without sufficient hardware, a YouTube recording is here: [this video] One of the guys who created this little gem gave a presentation about the technology behind it; slides are here: [LINK]
