The first time I saw a pic of the counterwith the 5 on Twitter, I thought Daved had a little ooops.

But the second thought was that the tube porobably wouldn't light up when put in in the wrong direction and this reversed tube was put in on purpose for a reason I don't knew.

It looks like Dave want to be absolutly sure that the counter will never have an overrun

The counter looks really nice.
What's missing now is an live-cam to show the couter.
Its always nice to see solutions of different people from different professions to solve one task.
I would have gone to the efford to cut out a small, tight fitting holes for every single tube.
(And would have wasted many boards.)
The solution Dave took is faster, easier, cleaner and looks really good.
