The original video this is paying homage to is a machinima by Dopefish. Baron Soosdon has taken that original exploration concept in hand and with Snoman's updated model-work, provides us with an interesting machinima full of beautiful music and lovely dark imagery. While I've no idea if it was intended, the imagery makes me think of the upcoming Wrath of the Lich King expansion. (I hope it looks half that cool!)
In any case, hats off to Baron Soosdon, Snoman, and Dopefish for their combined ideas that give us this lovely Sunday Break to enjoy!
