=== Squeak, Etoys, and Croquet ===
In December 1995, while still at Apple, Kay collaborated with many others to start the [[Open-source software|open source]] [[Squeak]] version of [[Smalltalk]]. As part of this effort, in November 1996, his team began research on what became the [[Etoys (programming language)|Etoys]] system. More recently he started, with [[David A. Smith (computer scientist)|David A. Smith]], [[David P. Reed]], [[Andreas Raab]], Rick McGeer, [[Julian Lombardi]], and [[Mark McCahill]], the [[Croquet Project]], an open-source networked 2D and 3D environment for collaborative work.
