"I think Alan's idea of OOP was something more fluid, more organic than this."

I've heard a good deal about Alan Kay's dissent of the state of OOP, but I've never seen a concise summary of his vision or the principles that Kay's 'ideal' realization of OOP would adhere to.

Does such a resource exist, written by Kay himself or otherwise? Or do I just need to go play around with Obj C or Smalltalk to really "get it?"
