Great video on chaos games, you can do a lot of these just using turtles in python. The wiki for barnsley fern covers this more. https://en.wikipedia.org/wiki/Barnsley_fern#Computer_generat...

The wiki for chaos games has animated examples that make it pretty clear how it works for the sierpinski triangle: https://en.wikipedia.org/wiki/Chaos_game

I enjoy that in Rule 90 of cellular automata approximate Sierpinski triangles are also generated as a mod-2 version of pascal's: https://en.wikipedia.org/wiki/Rule_90#Sierpiński_triangle Some other rules also result in the generation of sierpinski's triangle. Fun stuff.
