My friend Buxton has a massive clock. The clock module affixes to the wall and the numbers are stuck on individually. He's now moving house and is having some issues taking the numbers down. He merely enquired if it was possible to make clock numbers at some point in the future and 10 minutes later I sent him off with a whole new set, I like to think that's good service. I'll update when I get a photo of the newly installed clock.
Update 13th May: Buxton just sent me a photo of his massive clock, all painted silver and ready to go.
