+	Hello! Ultimately I don't care what you use this for. It's intended to be 
+	educational, and perhaps to the oddly minded - a little bit of fun. 
+	Please hack this, change it and use it in any way you see fit. You acknowledge 
+	that I am not responsible for anything bad that happens as a result of 
+	your actions. However this code is protected by GNU GPLv3, see the license in the
+	github repo. This means you must attribute me if you use it. You can view this
