Guess What This Is.

This is a photograph of a thing we have made in the shop. It is about 4 foot tall and is at the moment, blank. 

but what the hecking flip is it?

Yes, it's an 'ometer of some sort, but what sort? There will be a rather lovely book related prize for the best  (not necessarily the correct) guess. We'll finish it over the weekend and announce what it is on Monday or Tuesday next week.  

That's all.
