Enormous 3D Daddy Longlegs Mural Under Seattle’s Space Needle

If visitors to the Seattle Space Needle happen to look down, they’ll see two enormous daddy longlegs striding across the roof of the nearby armory building. The terribly convincing arachnids are actually a tromp l’oeil mural by artist Marlin Peterson. The process of making this anamorphic 3D mural was quite involved—Peterson created this video to show how he did it.
