TIL. In April 1974, in the middle of the night, a small group of conspirators secretly installed a large tensegrity icosahedron made from discarded telephone poles on the campus of Twente University in the Netherlands.

It’s still there. People call it Het Ding (“the thing”).

@robinhouston do that in the United States and the SWAT and bomb squad will show up
