The demo is available on shadertoy as unlisted here: 
https://www.shadertoy.com/view/WcB3Ry

Getting a proper recording from shadertoy is somewhat annoying,
so I've included a pre-made recording as well as instructions on
how to make your own.

In order to record the demo properly:
 - Install the "Shadertoy unofficial plugin" browser extension
     This is required for media controls to work in fullscreen mode
 - Open the shadertoy page
 - Press the "Reset time" button below the video to fix the sound
 - Wait for the demo to play for 60 seconds to get a black screen, do not pause it
 - Enter fullscreen mode and move the mouse into a corner so that it's hidden 
 - Begin your recording, do not use the built-in recording button,
   as it doesn't include sound correctly
 - Press Alt+Down Arrow to restart the demo
 - Let the demo run for about 30s (you can end it after a few seconds on the green text)
 - End the recording

I've also included an export made using the "Shadertoy unofficial plugin"
browser extension, which can be imported again using said extension, or
run locally with various programs, non of which have been tested. This is
mostly to show that the demo can be packaged into a single "executable" file.
