An original software implementation of a physical world inhabited with arti
ficial creatures is discussed. A creature is built of sticks, which play ro
les of affector, control and effector units. A structure of every creature
is recurrently described by creature's genotype The creatures either sponta
neously evolve or they are selected directly Originality of fundamental ide
as related to creation and evolution of artificial creatures, accuracy of p
hysical simulation of creature interactions with environment, user friendly
interface and great potential for graphical representation of the results
of evolution make the software a unique product on the market of artificial
life goodies.
