Here are the finished boxes, with a colour variation. I like them but am concerned now that they may be too complex for the hands of a clock to appear against. Here's one of those classic examples of form vs function. How awful it would be if someone were to say … "Nice image, pity I can't read the time!" I'm thinking that if I call this a clock then I am duty bound to put the function first and have a simpler, more readable clock face …… back to the drawing board.
