Description

Analog style watch.  
The rings that radiate from the middle of the display are for the hours.  These change from the background to foreground color as the hours increase.  
As the hours light up, they include smaller rings positioned appropriately as per an analog display (this creates the Phi-like spiral). These are filled to show the 5-minute positions and these continue beyond the hour rings if the 5-minutes exceed the hours.  The 5-minutes are displayed in the inverse colour to that of the hour rings.
Single minutes are show by four smaller rings that appear in the twelve o'clock position, again with inverse fill as the minutes increase. 

There is a choice of foreground color on the configuration page.
  
Screenshots show:  9:31, 12:59, 7:45, 8:04
