Teenage Mutant Ninja Turtles Projection

Found this video on Chris Diclerico's blog today.  Apparently a Brazilian agency called Ginga Interactive created this full-building projection to promote the new Teenage Mutant Ninja Turtles movie.  I was suspicious when I first read the blog entry [I've seen a lot of projection buzz lately and I'm not a TMNT fan], but must admit that this is very well done.

Not sure what's more clever -- the projection itself or the fact that the agency is distributing a video of people's reaction to the projection ...
