|Squeak :: Livecoding with Objects|
Squeak is an open-source implementation of the Smalltalk livecoding system. You can use it to build interactive software systems and change them as they run.
Squeak runs on the web (below), macOS, Windows, and Linux. The object memory running here is Context, a project of mine for producing minimal systems that federate for distributed computation. The official Squeak site is squeak.org. I blog about livecoding at thiscontext.com.
