Typogenetics is a recursive logic system in which strands of 4 
different units (A,C,G,T) generate "typoenzymes" which modify the
strands which generated them, and so on, often resulting in large,
diverse populations of strands.

There was a paper by Harold Morris in ALife I in which "Typogenetics"
(originally invented by Douglas Hofstaedter, as far as I know) was 
discussed in much more depth than previously. I've also seen a paper
on Typogenetics by Louis Varetto - this appeared a couple of years ago
in the Journal of Theoretical Biology.

Is anyone out there still interested in this stuff? If Typogenetics 
could be expanded into some kind of "Typoembryology", where in 
addition to modifying strands, typoenzymes could direct some kind of 
artificial developmental process, it could be very interesting.
Although this thought seems interesting to me, and I've played a bit
with unextended Typogenetics, I don't know where to start with my
Typoembryology idea.

Any suggestions? Thanks!

Perry
