This was an interesting concept.  lostcat461 wanted to see himself transforming from a human to a raver canine, and we also decided to have his outfit change along the way too. Basically it's the magic of music! I came up with the idea of focusing on specific parts of the transformation along the way, utilizing the lighting, and silhouetting the rest. The full canine form isn't revealed until the end.

So it took some creative effects with Photoshop, but ultimately it was a lot of fun. Some of the white pixels from the cut and paste remained, but I left some of them in since there's the silhouetting and light FX, they kinda fit. Hopefully the end result makes sense.
Not-so-suprising-fact; I've never been to a rave, so it took some poking around online...
