This here’s a special camera. When you press the shutter, it doesn't take a picture for you, but shows up on the camera of the next person who takes a photo here. This way, you’re forced to see through the previous visionary’s eyes. You’ll catch a one-frame glimpse of what they found beautiful or fascinating. Also, whenever they finally cut down this rotting tree, or tear down this old school, or clear this overgrown lot, it won’t be gone forever; at least one more person will get to see it. Which is exactly what a picture is meant to do anyway.
