Thanks Tom,
The E1T clock is at: https://www.youtube.com/watch?v=J5I_L4KY4Qo The video doesn't show it well but there's a little IN-17 nixie on the front that displays the number of satellites seen by the internal GPS receiver. It was a nice technical challenge but to be honest I don't think it succeeds as a clock. We humans are over-experienced to recognise traditional clockfaces and digital displays without actively thinking about them. The E1T is too alien. Non-nerds don't recognise it instantly as a clock as they do all the others I've made and even when it's explained people don't see it as a practical clock. Thanks for the offer of the transformer varnish etc. I've got a couple of other avenues to try (not work related :-) but I might get back to you.
