The original shader is a single raymarched scene which means that demo is very demanding on the GPU. But you can provide a scale factor for the framebuffers on the command line to get acceptable framerate.
The binaries are compiled for Windows 10 and can be downloaded here.
I suggest putting on some nice background music like Röyksopp for maximum effect.
If you're not that into VR you can go over to Shadertoy and watch the intro instead, https://www.shadertoy.com/view/4dcSDN.
