Short summary
State-of-the-art scientific drilling frequently involves X-ray scanning to get an initial overview of the recovered cores. The X-ray scanner generates a huge 3D image, usually explored with a specialized computer located several meters away from the cores. We suggest using paper summaries of the X-ray images for a more focused description without digital distractions. In particular, we propose creating a virtual image that wraps around the core, similar to how the Shroud of Turin shows a body.
