Someone pointed this out to be just minutes ago. Honestly, you'll be saying f^ck me, 4096 bytes

Unless you have a very high-end windows system you're best advised to just watch the video. I was impressed with the exe and thought it was a series of static images until I watched the video realised it was full motion as well

Here's the blurb anyway:

for those wondering, this a low density flat mesh displaced with
a procedural vertex shader. there arent any texturemaps for texturing,
instead texturing (and shading) is defferred and computed procedurally
in a full screen quad. this means there is zero overdraw for the quite
expensive material at the cost of a single geometry pass. then another
second full screen quad computes the motion blur. camera movements are
computed by a shader too and not in the cpu, as only the gpu knows the
procedural definition of the landscape.

I've been reading his website (http://iquilezles.org/www/), there's some really scary maths there. Puts my basic trig to shame anyway

So does the DX library fit in the 4KB limit too?

The exe's crashed on my machine. Am I missing something?

I've seen nifty graphics stuff in 4k before and this is no exception. The music is procedurally generated as well? That is the most amazing part, imo. I can't believe they can procedurally generate nice sounding instruments.

Procedurally generated instruments are nothing new, but in less than 4k? That's pretty impressive. I'm paranoid to run the thing in fear of viruses and stuff.

I do have a high-end Windows machine, but I can't run it. It crashes instantly.

[edit]

Nevermind, I never got the DX SDK after I reinstalled. This is fantastic, I can't believe how much they crammed into such a small package.

It needs to buffer the video off the server first.

I guess these are the hardware accelerated equivalent of the old DOS 64K demos. Pretty impressive.

It crashes for me too :/ But looking at the video it's impresive

I doubt there was enough space left for a virus.

4k is, in fact, smaller than the GCC-compiled 'hello world' program. Is this written in assembler, or just optimized near unto death?

It's not. MIDI is just a control data transmission protocol and highly inefficient at (it wastes a lot of bits) that. What you hear is very basic subtractive synthesis.

My computer doesn't handle it quite as nicely. (All I can see is a white oval that gradually gets darker towards the edges of the screen [so just that effect that makes the edges darker, with no actual content])
I did get some nice music, but I noticed exactly zero difference between it an the one on the online video.
