+# sierpinski-plotter
+
+Implementation of the Sierpinski Triangle [Chaos Game](https://en.wikipedia.org/wiki/Sierpi%C5%84ski_triangle#Chaos_game). Instead of outputting to an image, it sends HP pen plotter commands to a serial port. Tested on the HP7440A, but probably works on others.
+
+## Output
+
+I think this is 12000 points or so? I let it run for a while, then I added the code to allow for watching progress, and then I let it run for like, 6-7k lines. It probably ran for 2-3 hours in total.
