Thanks for posting about this work! But please, would you mind linking to the original video, http://www.youtube.com/watch?v=j9JXtTj0mzE , in the okreylos channel? The one linked here is an infringing re-upload. I'd like to keep comments on the original video instead of having to hunt them down all over YouTube. Thanks!
