Jim Seller’s made this amazing box full of gorgeously-machined art-widgets as a gift for a friend. It doesn’t actually do anything, except make people feel really good looking at the craftsmanship and love involved. Jim wanted to make something in the style of a 19th century scientific instrument. He calls it the ETD (Earth Tremor Detector).
I want to know how you get to be a friend of Jim Sellers. Hopefully this post on MAKE is a start.
