Here is a beginners look into Data tree management.

Also I sort of meant to redo the first algorithm but after a while I went a little more freestyle to cover more topics.

If you are wondering how I made the renderings at the end, I made the algorithms spit out hundreds of different iterations and save them in a specific folder with a specific naming convention. I then wrote a code inside of modo, that looked into the folder and replaced the geometry in every frame of the animation. Took me a very long time to figure out and just in case anybody ask, no, I do not give the code out, figure it out on your own.
