## Challenge #420: The Sierpinski Triangle

12 - Quasar

Great challenge to learn that ST_RandomPoint() is a function that can be used in the formula tool.

9 - Comet

My try :) This was a great challenge, thank you, @RWvanLeeuwen!

I also didn't know about ST_RandomPoint function.

Upped it to 10K iterations to make it show better - what an interesting phenomenon!

Thank you,  @RWvanLeeuwen!

This was a unique and interesting challenge. I did not know how the Sierpinski triangle is built until now.  Thanks for sharing.

I leveraged your approach in building my solution.

sorry, I forgot to include the workflow & macro, here they are.

My solution. I created it using my own approach focused on creating the Sierpinski Triangle without following the start file text.

Spoiler
I don't use the random function. I created three triangles from one triangle and processed them recursively.

This sample output is made from repeating 10 times.
