Oh Wow!!!! This is incredible and so beautiful at the same time. Those 3D Microscopes are wonderful inventions. Thanks for posting this, Dottie. See you again soon. Hope all is well. :)

Dottie, thank you for this nice puzzle. The 3D microscope has a tremendous potential in science and engineering. Specifically, also in criminal investigation...looking for hair, debris, etc. Haney :-)
