WIPE! ROTATE! PINGPONG! JUMP!

There's a sign at the Silver Spring MARC Station, I can see it from the platform of the adjacent Metro Station, which flashes a series of words and scrolls messages. I'm continually amused by several of the words that flash accross the screen. I've taken pictures of a few of them to share here.

As much as I am amused by the sign, I do question the wisdom of flashing the word "Jump" next to a railroad track.
