Having recently heard something about chaos theory, I was interested in the Sierpiński triangle. Specifically in the random generation. To prove that it can really be generated using a die, I wrote this program.
How it works
- You start with any point inside the triangle (I chose the center).
- A triangle has three points, let us call them 𝐴, 𝐵 and 𝐶.
- You choose randomly between one of those three points, go half the distance and set a pixel right there.
- Repeating this process over and over again (always starting at your last point), you eventually  get the Sierpiński triangle.
- ‘Space’ toggles if the triangle is generated,
- ‘m’ toggles if the current position is shown (indicated by a blue circle).
