## Lindenmayer Systems

By Daniel Kuebrich

Lindenmayer Systems (or L-systems) are rule production systems which generate certain patterns (notably tree structures and fractals) commonly seen. A little about L-systems: http://www.biologie.uni-hamburg.de/b-online/e28_3/lsys.html

### Usage

- Under the `Draw` tab, enter the angle and the distance (the length of each line), and press the `Set` button.
- Under the `Rules` tab, enter the seed and the production rules
- Enter number of expansions and click `Calculate` to expand the rules into the symbol string.
- Press the play button on this console to interpret the symbol string and draw draw the result.

You can also load rulesets with the `Load` button. There are several example rulesets in the `mason/sim/app/lsystem/` directory. Each ends with the `.lss` extension.
