A slate statue of Alan Turing at Bletchley Park museum.Bletchley Park Trust
Popular Science has a good story about the recent Turing test "victory". It also talks about the "uncanny valley", another point on the man-machine interface.
The statue shown above is kind of cute, using slate instead of cardboard, it reminds me of 3-D sculpture puzzles. It's a crude example of a digital representation of something from the analog world. It's crude enough that you know it's only a representation, not the real thing. That is not always the case with today's digital technology. CNC milling machines can now create round objects that are indistinguishable from lathe turned objects, at least to the touch.
