The "What's That Architectural Detail?" Game

I have been busy/uninspired, and that seems to have led to neglecting Architectural Appetite - poor thing. And to think I would do so right before Open House New York, which is sort of New York City's Architecture Appreciation Day(s). Well, sorry not to remind you of that until now - maybe next year?

Anyway, the Museum of the City of New York recently announced that the first phase of their $97 million dollar renovation is complete! The project is being taken on by Polshek, and the completed phase includes a 3,000 square foot glass pavilion, and an expansion underground. Probably safe to build below instead of above, considering the original MCNY building is a landmark and undermining its original structure is mean. (Does anyone ever notice the landmark that's under the Hearst Tower? Are you asking yourself "what landmark?" Exactly.)

In reading about the renovation, I came across this image:


I have been racking my brain trying to figure out what that thing coming down from the ceiling could be. It's kind of in the shape of a vacuum cleaner, no? Or a foot? Maybe it's a desk that has the ability to shoot files up to the second floor? Or maybe a display case? If anyone knows or can figure this out, please let me know so I will be able to sleep tonight.
