• the geometry is *really* simple meaning you can trace a shitload of rays without doing anything special (so doesn't take too much space either), so I'm not that impressed by the technical side. But the music and direction, oh, the direction!

• cupe: I don't think there are any NaNs, or pitch black that shouldn't be there - remember there is only a single bounce (with 4 rays per pixel in the normal version), so you can't get too far away from lit surfaces. If there is a problem it's more likely the random distribution that may miss some directions.
  You are right that the lightning from the balls looks a bit weird sometimes (especially when a new one pops), I'll mostly attribute that to the nature of the ball field (as also witnessed in the shadows in the first ball scenes before they are turned on - especially in the (old) youtube version), and probably exaggerated by the lowered precision for diffuse/shadow(/diffuseshadow) rays.

• The needed transformation is described here: https://developers.google.com/vr/jump/rendering-ods-content.pdf
  
  So, instead of the normal perspective ray setup:
  
  Code: vdir = normalize(rotatey(rotatey(float3((1.*DTid.x / WIDTH - .5) * aspect, .5 - 1.*DTid.y / HEIGHT, 1).yxz, pitch).yxz, heading))
  
  I do: (skipping the pitch rotation as it just makes you sick anyway)
  
  Code:float h = (DTid.x*1. / WIDTH - .5)*6.283 + heading, p = (.5 - frac(DTid.y *2. / HEIGHT))*3.1415; campos += float3(cos(h), 0, -sin(h))*.02 * ((DTid.y>HEIGHT / 2) ? 1 : -1); // small world - 4 cm eye spacing vdir = float3(sin(h)*cos(p), sin(p), cos(h)*cos(p));
  
  Quite straightforward in a raytracer - doing the stereoscopic 360 for a normal rasterizer would be a lot more involving.
  
  And then "just" render out to a movie stream in 3k*3k*60hz :)

• Since this wasn't specifically announced as 1k in the compo, I mostly had the feeling of "why make a worse remake of elevated", but as 1k it totally rocks.
