You may or may not have seen the gif that’s been going around of microscpic footage of a needle in the groove of a record. Either way, this video is a real treat. This fellow has a scanning electron microscope in his shop (no big deal) and in the video describes how he made the gif – and images a few more physical media formats as well. I love his casual attitude, even when using a freaking scanning electron microscope!
