AIMTalk is a program written by Chris Sims and David Karandish for Windows operating systems. It is a program that speaks to you whenever someone sends you an instant message via AIM. It has a rather strikingly similar sounding voice to Stephen Hawking, and knows amusing abbreviations like stfu and rofl. As of the writing of this, it is available for free download (at www.encore-designs.com/aimtalk) for a one week trial, but then must be registered for continued use.
