This a the light version of Tiger (which can be found under
the name of automate8e in the Emperor package, on aminet:dev/c)
Both  were made with Emperor, the .project file generated
by Emperor is also included. A french translation is also
included. 

No installation, just put the drawer wherever you want.
Versions for 68020, 68030, 68040 and 68060 (fpu required for all)
are provided, but you can compile any version you would
like (with StormC 3).

This cellular automata was part of my diploma work in Biology.
It is supposed to illustrate the creation and evolution of
a certain type of vegetation structures called tiger bush,
which can be found in various dry countries (Africa, Central
America or Australia).
The creation and evolution depends mostly on two parameters:
the slope and the rainfall. The slope must be low (less than
1.5%) and the rain must be concentrated over a few months only
(typical from dry countries). Another important parameter are
the termites. They build their houses which have a big impact
on the landscape and the slope (you can imagine termite-hills 
5 meters high in a nearly flat landscape). As they are getting 
old and forsaken by the termites, the termite-hills are being
degraded by rain, wind or any other ecological parameter. Then
the material can be moved up to a certain radius (usually 10 
meters).
In the cellular automata, you can change the slope, rainfall,
number of termite-hills, their maximal radius after destruction,
as well the x and y sizes of the simulation, plus the number
of generations you want the simulation to run.

Contrary as in Tiger (the full version), the images are not
saved on disk. When in Tiger all the generations where kept
in memory to allow to play them later, in Tiger-light only
2 generations are kept in memory. The memory consumption
is thus very small. With Tiger-light you can make it compute
as long as you want, but you won't be able to have an animation
at the end.
Another difference is that you can't put termites. They wouldn't
give a nice tiger bush anyway (and I'm not motivated to work on 
that, it's just giving tiger bush all the time, that's a bit 
frustrating even though it was supposed to do so).

Choose the version that suits you best.
