This is really neat. I've only looked at the first specimen, the very first specimen!, but that alone is pretty cool. The resolution is good, impressive even, but I can't get close enough to look at cleavage / fracture on individual clasts like I would with a hand loop or plain light microscope. Maybe have select areas of hyper resolution?

The mesh is good too, not perfect, but really much better than I have seen before. That's a lot of polygons to render!

The interface is fun. Options for orientation, zoom, scale, grid, lighting... Well done!

I am most impressed by the Micro X-Ray Computed Tomography. That shit is cool! I've been watching this developed over the years and I am really impressed. I wonder how expensive this technique is, because I've got a whole lot of samples I'd love to slice up this way, including nodular sillimanite gneiss (NSG), my name-sake. Or folds or fossils. This is really useful. One can download individual slices and do all sorts of mineral counts, fabric analysis, sorting, angularity, size. Yeah, you could do real research with this data.

Some things I'd like to see included are chemical analysis and petrographic thin sections. I know that this first specimen is historic, so it wasn't cut, but others were. Having a web viewer of a polarizing microscope would be great!

This type of interface could be used to create a database of typical geology 101 samples for online learning and study. Or as part of professional articles and presentations.
