Figs o' Fig
by Jonathan Pezzino

Figs o' Fig is an amazing graphics program
that is able to draw a user-designed figure
such that all the lines of the figure are 
actually composed of smaller versions of the
figure itself (like a fractal, but finite).

==Setting up Figs o' Fig==
Send the file FIGSOFIG.8xp to your calculator.
Before you will be able to run the program you
will need to design your figure.

==Designing Your Figure==
FoF figures are stored as lists that are in a
special format. Each element in the list is a
complex number that represents a vector where
the real part is the magnitude and the imagi-
nary part is the direction in degrees or rad-
ians (it is up to the you whether you want
to use radians or degrees - simply set your
calculator to the desired mode). Imagine your
figure is starting from a single point; the
vectors in your list will determine in which
direction and how long the next line in the
figure will be starting from that point. The
next vector in the list is used to draw the 
next line in the figure from the endpoint of
the line that was just drawn, and so until all
lines in the figure have been drawn (which is
determined by how many elements are in your
list). If this sounds incredibly confusing to
you, don't worry, it will become clearer when
you look at this example of an equilateral
triangle:
{1+60i,1-60i,1+180i}
This list, incidentally, was the list used to
draw the triangle figure in the second screen-
shot. As you can see, the first vector has a 
magnitude of 1 and a direction of 60 degrees,
which forms the first (leftmost) leg of the
triangle. The next vector is also a magnitude
of 1 (since equilateral triangles have legs
whose sides are of equal length) and a direction
of -60 degrees, forming the second (rightmost)
leg of the triangle. Finally, the third vector
has a magnitude of 1 again and a direction of
180 degrees, forming the 3rd (bottom) leg.

Wrap-up Notes on Designing your Figure:
*The best way to think of the list is directions
for a super precise etch-a-sketch that draws
a line of the length and in the direction you
specify.
*Once you have made your list, store it to list
VECS.
*It is best to use a maximum radius of 1, regardless
of how big you want your figure to be (it will
be scaled up however big you want it later on).
*Some example figures just in case you absolutely
cannot decipher this tutorial:
Square: {1+180i,1-90i,1+0i,1+90i}
Equilateral Triangle: {1+60i,1-60i,1+180i}
Star: {1+72i,1-72i,1+144i,1+0i,1-144i}
Squiggle: {1+50i,.5+0i,1-50i,.5+oi,1+50i}

==Using FoF==
Once you have designed your figure and stored it
as list VEC, it is now time to run FIGSOFIG.8xp.
For your scale, enter something that is close to
your total y-scale. (For example, if your y-scale
were [-6,-6], a good scale might be anywhere from
10-12.) Next you will be asked for figs/line. This
is the number of figures will be used to draw one
line in the "super-figure." Remember, the more
figures per line will distort the smaller figures
while making the larger figure clearer. The opposite
is also true. Next, choose a point on the graph
that will be the starting point from your figure.
Usually the upper right or lower left corners will
be the best areas to select your point, depending
on how you designed your figure. Press enter, and
the program will take over from there, producing 
that coveted drawing you have worked so hard to design
and see. If your figure looks distorted, try quitting
and pressing [ZOOM][ZSQUARE] or reducing or increasing
the number of figures per line, or adjusting the
scale. If your figure appears to be going off the
screen, try selecting some different points on the
graph to see which produces the best results. You
may also want to change the appearance of your figure.
Don't be afraid to quit and make adjustments to list
VECS.
