Lively will seem vaguely familiar to you if you've ever run Smalltalk. That's not an accident:
The idea of the Lively Kernel was inspired in part by the success of the Squeak Smalltalk programming environment. In this regard, we owe a debt to all the people who designed that system. The specific choice of a Morphic-style graphics architecture was inspired by the simplicity of such an architecture manifested originally in the Self system and later in the Squeak system.
The irony of this being developed at Sun (Sun! Those Java people!) will not be lost on the former-bitter-ibm-smalltalker contingent.
