Well... I would very much like to see the source code... But I am afraid the documentation would have to be much bigger than 4kB to understand the dark magic. :) The size is incredible.

This video has been selected by our channel as one of the best Animation videos on YouTube and was added to the channel's playlist accordingly. Thanks for sharing.

I was high for 2 minutes and 49 seconds

whoaaa... trippy...

I really love it, it's amazing :)
The synchronizing of the music and the video is great!

Some day I will stop being lazy and attempt to make one of these smaller sized demos.

you are wrong

Are they loading a bunch of libraries from their 4k of code?

this intro in basically rendering one triangle on the screen and the visuals are then calculated in realtime by a pixel shader.
the music is done with a software synthesizer and also calculated in realtime, its not using midi or mod/xm.
the whole stuff is crunched with a packer in the end resulting in an exe file smaller than 4096 byte

Is there randomness involved? One commenter mentionned the use of unsmooth surfaces, which can be used instead of textures with the correct lighting. That sounds like it could be generated randomly instead of being mapped. Is the intro always the same, or does it change with every play?
