It baffles me how anybody can republish something they didn't create and not take the time to cite where they got it from. I know it's not the intention to steal (at least I hope it's not!) but it's not hard to do. You're not asking for money or anything difficult to provide, just credit where due :-)

Oh, by the way, did I mention that I created that video? OK maybe I only watched it and had nothing to do with its creation.
