So it is really a variation on the 'Bubblegram' 3D laser printing in glass: https://en.wikipedia.org/wiki/Bubblegram https://en.wikipedia.org/wiki/Bubblegram The '5D' comes from the size and the orientation of the bits that get fused together deep in the glass. The original 3D printing in glass came out of Russia, so it is interesting that this '5D' science is kind of Russian. I think that with 3D laser printing in glass there was always a problem of 'what use is this?' and I am wondering if that quest resulted in the Asimov ideas and the pitch to SpaceX etc. I do not think that it is at all obvious that 'size' and 'orientation' matter to our binary trained brains, so making a machine capable of reading the disc and then reading it and then getting the schema right is a bit of an ask. The HotWheels toy car with Spaceman is the merch they need to be selling to get donations for this.
