A nifty looking device, but I don't see how it meets the requirements of a
Turing machine.
"The language of the machine consists from some simple instructions like: L-
for moving the head to the left, R- for moving the head to the right, the
"symbols"- for writing the symbols on the tape and the "variables"- for
writing the variables." (http://www.glissando.net/vturing/)
I don't see a mechanism in the robot that'll write or erase just one bit.
The motor on C would seem to twiddle the bricks, but that impacts the entire
stream.
Am I missing something?
