Once I saw this concept I couldn't not make this... I mean, I had to keep this project a work lunchtime thing JUST so it didn't infringe on projects at home. I would turn up to work early, or go home late.. just to do an extra hour on this. Super fun. I have no life. I think because it is so different from what I normally produce it was a breath of fresh air... sorry about the gradient banding and video compression :\

Video rendering in Unity is super easy and you will have no problems :)
