WIP: Regenerate all examples with a script

This is part of what I want to do in issues #66 and #67. The next step is to make assertions on the generated output, so that I can catch regressions. TODO: There are massive diffs with every run of the script. I suspect there's something nondeterministic about the ordering of geometries?

 We can see that the flat format _does_ save time, but not by a significant enough amount to make it worth while.

 I intend on implementing a few more techniques because for this kind of geometric data, none of the above techniques work well with 3D data.
 PCA and SVD work pretty well on 3D data with a missing component (like the Sierpinski tree example).

 # Generating Random L-Systems
 
 Using the [random-production-rules.py](tools/random-production-rules.py) tool, you can generate random production rules.
-Notice that in many of the following examples, I've used `tr`/`sed` to edit the generated rules.
-Most of the generated L-Systems aren't interesting, and many of the ones that are, use `d`/`D` and `f`,`g` liberally, so they don't actually generate an image.
+
+In the following examples, I've generated many random L-Systems, and saved the configuration for ones I like in [examples/random-lsystems/saved.json](examples/random-lsystems/saved.json).
+Alternatively, you can just use [examples/random-lsystem.sh](examples/random-lsystem.sh) to generate and render random L-Systems of your own.
+It will output the configuration in JSON, along with the random seed for reproducibility.
