Holy Crap What Is Happening To This Air Vent?

Yeah, a Mercedes S-Class may have perfume wafting through the cabin, but does it have awesomely spinning vents? Just turn it up, flick, and watch it go. This is weirdly, oddly, amazingly satisfying to watch.

I'm not sure if this was an intentional feature in the 2001 Pontiac Grand Am, but it definitely is one of the greatest I've ever seen. Is a very fast mouse stuck inside? Is it hooked up to a small airplane engine?

Or if you put something through it will you see the ghost of Carl Sagan, but if you try to record it you'll only get 18 hours of static?
