Slide iterations to change how long program runs. More iterations give a more detailed triangle. Red vertexes are draggable. Cool things happen if you drag the red vertexes while the program is running. Click space to run program. Click A to run program as fast as possible. Slide time to change how quickly the program runs. The run duration of program is determined only by the time slider when space is pressed, not by iterations. The program can reasonably handle up to a million iterations, but the picture doesn't look different for any number greater than 200,000. This is partially due to Scratch's minimum pixel size, I believe.
This triangle is actually generated via a random walk! The process starts by picking a random point in the triangle. Then, travel toward a random vertex of the triangle but stop halfway. Put a point there. Repeat indefinitely. This process approaches Serpinski's Triangle as you can see! There is a very good mathematical reason behind this.
