I was mainly thinking of making some recursion hence why all the subclocks mirror the parent clock (for that given hour). Also I called it clock squared because I didn't think the resolution would be high enough for people to actually notice the 3rd level of clocks.

You might notice that some dials don't really align with the hours they're supposed to show. That's because I had to place a bunch of clocks at varying hours with a viewport rendering the parent clock at an angle that probably made it difficult to spot the errors. I rendered it once and didn't bother re-rendering it once I saw the errors :)
