Hank Green is the narrator of "Journey to the Microcosmos," and he and the people involved made a Kickstarter project to provide decent microscopes for people who may be interested. The Kickstarter campaign is done (I bought the book), and the videos are now Hank describing what stage of the process the microscopes are in, and showing off what they've made. I enjoyed this:
This reminds me of myself like 14 years ago, finding the microscope my grandmother gave to my father, and playing around with it, sticking all sorts of stuff under it. Now I know approximately what my friends and coworkers were experiencing while talking with me.
