Saw this gist on Reddit! Amazing work, OP! <3

Could you proper license this code? I would love to make some tweaks and maybe even package this for distribution! You may take a look at: https://choosealicense.com/

@Hinigatsu you can do anything with it
btw this code is a part of another project I think you will be like it too.

Oh, that's nice! Thank you for the link <3
