# Context Free

I recently discovered Context Free, a nice program for using simple mathematical models to create some pretty interesting graphics.

I recommend visiting the gallery to get a better idea of the what I am talking about.

Additionally, I will throw up a few examples of my own experiments here.

# Nautilus Star

Here is the code:

```
startshape ring
rule ring {
line {s 0.4}
ring {
x -0.5
y -0.133974596
r 30
s 0.935
}
}
rule line
{
CIRCLE { }
line { x .5 s 0.99 b 0.01 }
}
```

# Nautilus Shell

And the code:

```
startshape startnautilus
rule startnautilus {
nautilus {
r -45
}
}
rule nautilus 100 {
SQUARE {}
nautilus {
s 0.9983
x .3
r .5
}
}
rule nautilus 1 {
SQUARE {}
nautilus {
s 0.998
x .3
r .5
}
divider {
s 1
y 0.3
r 23
}
}
rule divider {
SQUARE {}
divider {
s .9735
x 1
r 1.5
}
}
```

# Golden Triangle

```
startshape left_fold
rule left_fold {
TRIANGLE {}
TRIANGLE { s 0.95 b .7}
left_fold {s .75 x .55 y .16 r 60 b .15}
}
```

# Golden Textures

This one is not mine (written by a user named lagroue), but I like itâ€™s use of color. Check out the original source.
