Engadget has a report on Scion's latest advertising campaign—and it's a doozy. The report said that in an effort to market its limited-edition tC Release Series 4.0 coupe, Scion partnered up with interactive outdoor advertising company InWindow to cover a series of street-side windows with bubbles, which reacted to movements made by "captivated individuals walking by."

There's a (blessedly short) YouTube video demonstrating how it works, along with some passerby interviews saying that, in effect, it's neat. At least in the clip I saw, you don't get to see a whole lot of the actual Scion tC Release Series 4.0 itself (see above pic). Instead, you see a lot of bubbles flying around, in a way that appears sort of tied to your movements, but not exactly. Still pretty cool, though.
