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

Cheers!
