Me too, I went from thinking I sort of new something about how clocks work to actually understanding it properly for the first time ever, reading a small amount if text, again to get to the 'I get it' moment. I also think that this is possibly because this is a model of a real clock that really worked, once upon a time. So the WebGL model works as per the real world clock, not some 'example' model made from theoretical pieces.
