Vinyl through Electron Microscope

In this video Microscopy Specialist takes a look at a vinyl record, stylus, and cartridge under a hugely powerful scanning electron microscope (SEM) with up to 100,000× magnification and ~10 nm resolution! Most people are reasonably familiar with how records work, but seeing it in this level of detail really brings out the magic. Superb stuff... I wonder what else would look good under the SEM - what do you think? Here's more from the video... 
 

You'll see: 
• A stereo groove at extreme magnification • How left and right audio channels are encoded in one groove 
• Moving magnet (MM) vs moving coil (MC) cartridges 
• What mono records really look like 
• Why vinyl sounds "warm" and "airy" 
• Clicks, distortion, and inner groove physics
