That’s right. Julldozer of Mojoptix set out to 3D print a sundial with the question: “What if we had a sundial that worked more like some sort of enormous digital watch?” And what he means by this is that as the style on the sundial moves, sun is either blocked or it breaks through the design holes (he calls it “swiss cheese”) so that the actual time can be read in the shadow of the sundial.
