Well, I'm voting for the pics I interpurt to be on topic, all the macro shots didn't fit the objective in my opinion, so here goes! Number1. Supermarket spikes alef. Because I have never noticed these pidgeon spikes before, one has to look closely to see them, which fits the theme perfectly. Number2 Listening In mauvais mangue Because of the ring around the leg, one would have to look closley to differenciate a wild bird, to a tracked bird. Number3 Valve Springs exosculate Because, one would have to take close attention to a cooled light bulb, to actualy see how much work goes into making them. Good luck all.
