I got up this morning and saw this picture by Katie Scully in the Reader Flickr group.
I'm not the only one who noticed. Fortunately, she added a note; there's a caption, unreadable in the picture, which reads "Solve * RGB." Solve * RGB seems to be an artist, screen printer, and member of the RGB CREW, who participated in the recent art exhibit Echo Chamber 3: Resolutions. Here's more evidence of his or her existence.
Update: solved.

That's what they don't tell you about the El cars: there are outlets underneath some of the seats (I think just the ones parallel to the track next to the doors on the ends of the cars). I've seen people charging mp3 players from them.
Ah... thanks. Now I can save my shaving for the el ride to work...
