Creating fractals in Minecraft using Clojure with the Bukkure plugin.
To generate these triangles connect a repl to a Spigot server running Bukkure and run the following function within the fractalz.core namespace :
(make-sierpinsky-pyramid 128 "<The name of your player>")
Or from within the Minecraft console run
/sierpinsky 128
Replace 128 with the size of the triangle you want to create.
