A new pyramid-like shape always lands the same side up

Great article!

The excitement kind of ebbed early on with seeing the video and realizing it had a plate/weight on one face.

"A few years later, the duo answered their own question, showing that this uniform monostable tetrahedron wasn’t possible. But what if you were allowed to distribute its weight unevenly?"

But the article progressed and mentioned John Conway, I was back!

Made me think of lander design. Recent efforts seem to have created a shape that always ends up on its side? XD

Initially I thought it was unimpressive because of the plate. But then I thought about it a bit: a regular tetrahedron wouldn't do that no matter how heavy one of the faces was.
