A) The Nixie Clock - made of Nixie tubes. Not quite "Steampunk"- but getting close- digital numeric displays don't get much older. I'm fascinated by the Steampunk movement - i guess it's a nostalgia for the past's view of the future (as seen from the vantage point Victorian England). Perhaps there is a general class of similar ideas - the view of future year X as seen at the time of Y. How did the Babylonians imagine the year 1000AD? How do we envisage the year 3000 ? "Punk-Something-yet-to-be-named". I'm off to watch the "League of Extraordinary Gentlemen".
B) LED Clock from Jonas Damon available from Areaware.
