Remember the old science fiction movies, where they took a 2-inch lizard or tarantula and superimposed it into the scene of frightened people and cities being crushed? You just knew that Godzilla really was forty feet tall!
Check out this tree-like structure from today's walk on Duxbury Beach, south of Boston. In another setting, you might be persuaded that the photo above is of a large tree knocked over by a storm. But, no, it is just an interestingly shaped sponge, and, as you see here, merely a few inches tall.
Meanwhile, watch the video below. It is a little unclear, but if you watch closely, you will see a flock of birds just to the right of the SUV, turning and swooping as a group. As they do so, they show us bottom, side, and top views; and they go from nearly invisible to dark to shimmering white.
