Look Both Ways and Hold Your Partner's Hand
Taken specifically for the Weekly Themes group, for the "yellow" theme this week. (But also for the Mellow Yellow group, which I really dig, 'cos it taught me to appreciate a color I had neglected for my entire life.)
One of my flickr-friends took a photo of one of these a few months ago and I couldn't identify what it was. I thought it looked like a snack-cracker for robots! Since then, these have popped up all over my own city.
