By applying L-System fractal algorithms
to a 3-Dimensional trigonometric system,
I've come up with this program which
will generate 3-D L-Systems ( dig??).
Basically all you need to know is that
this a program that will create
plant-like structures using many
cylinders, often hundreds and sometimes
thousands.  You the user, with a proper
background(given below) in L-Systems,
can utilize this programs to create
almost any type of fractal, bush, tree,
curve, or whatever else you can think
of.

ALGED Algebra Editor by John Henckel.
This program is a tool for solving
algebra problems. You may ask yourself,
why do I need a computer to help me do
that? Well, it might not make sense for
small problems, but if you have a rather
large problem with several equations and
the result is a fourth-degree polynomial
that doesn't fit on one page of notebook
paper, then Alged can help. Alged cannot
solve the problem for you; you need to
think. But it can relieve the tedium of
working with large formulas, and it has
rewrite rules to help simplify as you
go.

Gravitational N-Body Simulation: 16 bit
DOS version by Henley Quadling. This
simple 16 bit Dos protected mode
application allows you to simulate N
particles which are subject to their
gravitational interactions, by clicking
with a mouse cursor directly on the
screen. Initial velocities and different
masses can also be entered. This program
will use every iota of floating point
power that your system has to offer.
There is no limit on the number of
particles; the speed of your fpu is the
only limiting factor. The calculation is
a true three dimensional calculation.
