[time-nuts] Hands on digital clock

It seems to me there is a way to make the segments folding so they could be 
changed without removing and inserting boards.  Kind of like a folding 
ruler.  I'll have to do some experiments with scraps of wood in my shop.  On 
a smaller scale of course.

When I was little I used to like forming letters and numbers with my dad's 
folding ruler.  I probably invented the 7 segment display without knowing 
it.

Regards.
