Playing around with L-Systems for #genuary2021

Genuary is a series of prompts to inspire generated art in the month of January. You can find a list of the prompts here: https://genuary2021.github.io/prompts

The prompt for today was "Curve only". This made me think of space filling curves, like the Hilbert Curve. One way to draw the hilbert curve is by defining a L-System, a notation that defines a recursive sequence of steps. So, I made a program that can draw L-Systems. You can select a pre-defined L-System like the hilbert curve, or my favorite - the dragon curve below, or click on the random generation button to try a randomly generated L-System.

The L-System definition can be viewed above the canvas. You can also adjust parameters like the recursion depth and whether or not some randomness should be introduced by the turtle on every line it draws. You can also enable or disable animation. Warning: don’t set a very high recursion limit of your browser may freeze or experience lag.

Note that every curve starts in the center of the screen, so some curves like the hilbert curve go out of bounds.
