Does this freak you out?
What about this?
Actually, I love these and was absolutely delighted that I happened to spot them, especially since it's now moss season again and they are looking at their spiffiest. I've walked by this retaining wall probably a dozen times, but it was usually at night, so I never noticed these mossy fellas before. They're very close to the ground, too (about eye level for cats, i.e., in the catmosphere), which also means that probably very few people ever notice them. But how great is it that the homeowner built these into the wall just for those of us who just happen to be a little bit obsessed with retaining walls?
