New York's Newfangled Crosswalk Signals?

Usually when most New Yorkers are crossing the street, we just look for oncoming traffic and cross - only occasionally looking at the crosswalk signals. Yesterday, Gothamist was walking to work when we looked up at the crosswalk signal and spotted something different. After doing a double-take, we realized that the signal was different than the ones that were introduced a couple of years ago. While the sign still had the red "don't walk" hand and the white "walk" man, they were presented in a different way: Instead of having the lights shaped like the man and the hand, the two symbols were screened onto the plastic surface of the signal.

We took a quick look at the rest of the signals in the intersection and on our remaining walk to work, but those were all normal. Has anyone else seen these signals, or is this one just an anomaly?
