There is a discussion about the new paper on the monostable tetrahedron. Discussion: https://news.ycombinator.com/item?id=44381297 https://news.ycombinator.com/item?id=44381297 I have the reference ancient model, and someone asked for photos so I knocked up this page to give some context and provide links to photos. Better photos to follow when I have time.
