"JohnnyVon is an implementation of self-replicating machines in \ncontinuous two-dimensional space. Two types of particles drift \nabout in a virtual liquid. The particles are automata with \ndiscrete internal states but continuous external relationships. \nTheir internal states are governed by finite state machines but \ntheir external relationships are governed by a simulated physics \nthat includes Brownian motion, viscosity, and spring-like attractive \nand repulsive forces. The particles can be assembled into patterns \nthat can encode arbitrary strings of bits. We demonstrate that, if \nan arbitrary \"seed\" pattern is put in a \"soup\" of separate individual \nparticles, the pattern will replicate by assembling the individual \nparticles into copies of itself. We also show that, given sufficient \ntime, a soup of separate individual particles will eventually \nspontaneously form self-replicating patterns. We discuss the implications \nof JohnnyVon for research in nanotechnology, theoretical biology, and \nartificial life."^^ . "2003" . . "9" . "1" . . "MIT Press"^^ . . .
