Interesting, on the Southern hemisphere, the sundial needs to point to the South Pole and the design needs to be altered:<p>&quot;in the Openscad script you can set a flag that will simply rotate upside-down the whole swiss cheese inside the gnomon, and build a ‘Southern-hemisphere’ version of the gnomon. This way, the ‘roo can simply use this Southern-hemisphere sundial exactly the same way a cow or a penguin would use their Northern-hermisphere version the sundial, with just one difference: the ‘roo will have to point the tip of his sundial toward the <i>South</i> Pole.&quot; [1]<p>[1] <a href="http:&#x2F;&#x2F;www.mojoptix.com&#x2F;2015&#x2F;10&#x2F;25&#x2F;mojoptix-001-digital-sundial&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.mojoptix.com&#x2F;2015&#x2F;10&#x2F;25&#x2F;mojoptix-001-digital-sund...</a>
