On the downside, if you want more information than "these two things are spatially close to one another", the Hilbert curve makes it difficult. Unless you have a map of the curve in your head, could you tell where in the file something in (say) the upper-right quadrant is? If folks are interested in Hilbert curve visualizations applied to live memory, this is something I implemented in PANDA a couple years ago and demoed at RECON: https://youtu.be/YGVnpWXtlF4?t=2919 https://youtu.be/YGVnpWXtlF4?t=2919 My conclusion was that I had no idea how I'd actually use such a thing, but it sure is pretty to watch values in memory changing on the Hilbert curve!
