gravitational mapping is so cool to me - that by detecting small minutiae in accelerations, we can map masses with precision!
Also, yes, the names "Ebb" and "Flow" are pretty cool.

any chance that future posts will attach metadata to the images? I'm sure you have the skills and the means. I'm hoping you have the desire to enhance the accessibility of your posts. It will benefit a big audience.
