Daniel Henry Holmes Ingalls Jr.: The Live Web. Drag 'n drop in the cloud
JSConf

Smalltalk pioneer Dan Ingalls presents the Lively Kernel at JSConf US 2012, a live, direct-manipulation programming environment running in the browser. He shows drag-and-drop building of live objects on the web.
Commenters link it as a demo of what a live, inspectable, Smalltalk-style environment in the browser can be, in threads about Alan Kay, Smalltalk and web limitations.
