Entropy Garden

Entropy Garden

en·tro·py

/ˈentrəpē/noun

1. Physics
A thermodynamic quantity representing the unavailability of a system’s thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system.

“the second law of thermodynamics says that entropy always increases with time”

2.
Lack of order or predictability; gradual decline into disorder.

Entropy is the general trend of the universe toward death and disorder.” —James R. Newman


I come from a family of 6, argumentative, opinionated, and curious. There is always a low pressure storm building, waiting to break out into an argument, debate, or spontaneous dance session in the kitchen.

My mother first introduced to the idea of Entropy. As her parents (my Opa and Nana) began to age, the reality of living in the remote high desert of Nevada became untenable. Their property required constant maintenance: including a well, first powered by a homemade windmill, then by solar panels he installed himself.

My mom, the oldest of her siblings, decided to build a house in our backyard for my Opa and Nana to move into. The Entropy House was born. This project, born from pragmatic love became a home for us all to experience the Entropy inherent in the process of life, death, and rebirth.

When Chloe asked for art submissions for her birthday gallery show, I knew I was going to take this moment to start my own blog (welcome :)) and I wanted to explore entropy. Beyond that I wasn’t I’ve never been confident calling myself an artist.

In high school, I applied to the Teen Arts Group (TAG) at the Seattle Art Museum to challenge that feeling of inadequacy. Lacking a piece of art to bring to the the interview, I brought my beat-up running shoes. I explained how the worn treads were a journal of my meditation across the many miles and places I’d been. I loved the challenge of finding art and meaning in something purely functional. That experience taught me that art is a matter of perspective and a willingness to look.

Every Thursday we made art, ate snacks, and planned Teen Night Out: a free museum party for teens with live performances, figure painting, and tours. My favorite project as part of TAG was working with a piece from the museum’s collection. I chose the elevator doors from the Chicago Stock Exchange, an exhibit I’d initially walked past without realizing it was art.

So I knew my submission, to truly come from me, needed to be a little odd. I am a technical writer and spend my days writing code, creating diagrams, and responding to jira tickets. I also spend a lot of my day thinking about how to improve interactions between government Open Data and Artificial Intelligence (deeply conflicte about this). I wanted a project that incorporated these parts of myself while pushing me to think about entropy, art, and my complicated relationship with modern AI.

I started by looking at different old school styles of Artificial Intelligence that were deterministic and stochastic, explainable, low energy, and understandable.

I landed on L-systems an early form of AI introduced in 1968 by Aristid Lindenmayer, a Hungarian theoretical biologist and botanist at the University of Utrecht. L-systems are a type of formal grammar where an alphabet of symbols is used to create strings using a collection of clearly defined production rules. You can then take these strings and translate them to geometric structures to model the growth of plants. They are an early attempt at artificial life.

Please interact with garden below! I created some initial templates for plants. Play with the colors, the stochasticity, line length, width, and the angles. If you are curious about creating new plants for the garden, change the rules to define your own artificial life (technical explaination follows below if you’re curious how to do that).

I do believe that technology is one of many tools we can use to help make our communities stronger. But I also think to do that, technology needs to be understandable, community driven, and beautiful. Enjoy!!

Explaination

What Are L-Systems?

An L-system (Lindenmayer system) consists of three components:

  • Alphabet: A set of symbols (e.g., F, +, -, [, ])
  • Axiom: The initial string (e.g., F)
  • Production: Rules: Rules that define how each symbol transforms (e.g., F -> FF+[+F-F-F]-[-F+F+F])

The system works by iteratively applying the production rules. Each generation, every symbol in the string is replaced according to its rule. After several generations, you get a complex string that encodes a branching structure.

Turtle Graphics Interpretation

The string is interpreted using “turtle graphics,” where an imaginary turtle walks and draws

SymbolAction
FMove forward and draw a line
+Turn right by the specified angle
-Turn left by the specified angle
[Save current position and angle (push to stack)
]Restore saved position and angle (pop from stack)

The [ and ] brackets create branching: the turtle “remembers” where it was, explores a branch, then returns to continue the main stem.

Deterministic vs. Stochastic

Deterministic L-systems produce the same output every time—the same rules always generate the same plant.

Stochastic L-systems introduce randomness by providing multiple possible replacements for a symbol. Each time a rule is applied, one option is chosen at random. This creates natural variation: no two plants are exactly alike.

Example: A Simple Bush

Axiom: F
Rule:  F -> FF+[+F-F-F]-[-F+F+F]
Angle: 25

Generation 0: F
Generation 1: FF+[+F-F-F]-[-F+F+F]
Generation 2: FF+[+F-F-F]-[-F+F+F]FF+[+F-F-F]-[-F+F+F]+[+FF+[+F-F-F]-[-F+F+F]...

After 4-5 generations, the string encodes a complex branching structure that resembles a bush.

Creating Your Own Plants

Try modifying these parameters in the garden above:

  • Angle: Smaller angles (15-25) create denser plants; larger angles (35-45) create more spread
  • Iterations: More iterations = more complexity (but slower rendering)
  • Rules: Add more branches with [+F] or [-F], create asymmetry with different angles
  • Randomness: Add percentage to create natural variation in angles and lengths
