I had no idea such a think existing until a few days ago when I was cruising around Flickr. I ran into a series of photos by a guy who was creating some fantastic stuff. And one of his pictures was of his Nixie Clock. It's a clock that uses special tubes that can show digits like this

It's really a beautiful thing. I have had a love affair with the tube for audio purposes and now for telling time too. I think that would look nice in my living room. Don't hesitate to head over to this site and buy me one.
