Experiments & cultural artefacts
Lab
Before the Institute, there was the Random Research Lab — a quieter name for the same instinct: that the goddess Τύχη, fortune and chance, sits at the root of cryptography and that the work most worth doing sometimes starts in a corner with a notebook rather than on the front page. The Lab is where that instinct still lives.
For peer-reviewable working papers and formal research output, see Research. This page collects the lab side: experiments, essays, and publications adjacent to the Institute's technical mission.
