I’ve always adored Rube Goldberg devices. It may stem from watching too much Tom and Jerry or Wile E Coyote as a young tot. Each of those fellas built some outlandish contraptions.
The origin of these machines dates back a century to Ruben Lucius Goldberg. At a young age, he obsessed with tracing from books, newspapers, and calendars. After a failed career as an engineer, he began drawing cartoons for the San Francisco Chronicle.
Perhaps the best device I’ve seen to date is “Page Turner”. Watch and enjoy.
