While I was driving out to the bike shop today, I was playing "spot the B box". These are the ubiquitous large metal cabinets next to the street, which are painted unassuming colors of grey, beige, or green, and which blend into their surroundings so well that they're functionally invisible. There's one every few blocks to serve the local area's telephone distribution needs... I managed to find almost all of the ones along my route across town, but with a couple of them I suddenly realized that the reason I couldn't see it was that
I was staring directly at it. Thus, the game to spot the invisible.
