Some days reality gets scary... It turns out that this has been
done with prosthetic hands. Testuya Higuchi at the Electrotechnical
Laboratory in Japan (who as it turns out is the boss of Hugo de Garis),
has put the circuits for "evolvable hardware" into the prosthetics
to allow a rapid speedup in training time.
See: Science News Sept. 4, 1999, pg 156-158.
Interestingly enough the article comments on the fact that de Garis
has his 72 gate array [= 70 million brain cell or 10,000 500 MHz
Pentiums] built but they are having problems figuring out how to
connect together the 60,000 circuitry blocks to actually "do something".
