I'm Curious What's Going on With the White Sand Device on Tall Dane

i'm so curious what they are using here we saw white sand be used on rishar for investiture measurement but in a much more primitive way. i just have this concept of like you should be able to use the exact same principles that we saw on rishor with white sand but get a digital readout of that information like this. obviously there are like foreseeable issues with that but it is vastly preferable to anything else.
