Stationary disk with 60 slots, with a rotating disk with delta 1 lines behind.
On a caliper, the vernier site of the scale has 11 increments for 10 on the main side.
Does it matter which side becomes the hand and which the background? Test...
to do
- better prototyping. maybe extension
- no easy documentation on cloning in scripting

options if current design does not work
- need to figure out the hours part... maybe spiral?
- could do the whole thing with only 5 minute increments and use hour speed
givens
- Clock mechanism
- diameter hour 5.75mm or 5mm (it has a step)
- diameter minute 3.55mm
