What a fun idea!
Is it on purpose that all clocks in this are coupled at the 3 o'clock position? I assume all the clocks go the same speed. Then the large clock and all the smaller clocks at the 3 o'clock position (there are 13 of them) would show the same time. E.g. in one hour, the 12 o'clock position would show 1 o'clock, but the large clock and all the clocks on the 3 o'clock position would show 4 o'clock.
Oh and why is it a clock squared if you have three layers of clocks? Isn't it cubed then?
Haha yes, recursion is always fun!
Although I'm still confused on what the clock would show in an hour. Because if the subclocks mirror the parent clock at the given time, then they would all be stuck to the hour they are positioned on? Or if they can move then the sublcocks are coupled to 3 o'clock of the main clock. But well, it is all hypothetical anyways :D
