What time is it? If you're at this skate park in Lugano, Switzerland, you don't have to check your watch or phone. Just look down into the pipe and see where the shadow is. The architects at the Moscow-based Zuk Club designed it like a sundial. As the shadow moves across the park, it notes the hour on an array of vibrant colors. You can see more photos at Web Urbanist.
