New York City Mayor Michael Bloomberg's animated sign language interpreter, Lydia Callis.

She's a Hurricane Sandy sensation, and she hasn't said a word.

Sign language interpreter Lydia Callis is giving New York City's beleaguered residents a reason to smile with her emotive, animated translations of the latest news on the superstorm from Mayor Michael Bloomberg, New York magazine reported.

Her whirling, lightning-fast hands have been described as "mesmerizing" and "hypnotic" by a growing fan base on Twitter.

Even stone-faced Fox News Channel's Brit Hume is fascinated, tweeting "On Weather Channel, woman signing for Mayor Bloomberg during his hurricane press conference is stealing the show."

Another user tweeted, "No making fun of Bloomberg's sign-language translator. Seriously. Only love. She's doing her job both very well, and with STYLE."

There's now even a collage of images of Callis mid-message. And demands for a fan page are growing.

According to NPR, Callis graduated in 2010 from the sign language interpretation program at The Rochester Institute of Technology's National Technical Institute for the Deaf — one of the best in the country.
