Nixie Tube Clock

I'm doing some research on some new projects that I would like to tackle. One of the most interesting ideas I came across was the Nixie Tube Clock. Nixie Tube Clocks can be viewed from the url i posted below containing further information. It looks like an extremely complicated project in which some materials might be hard to come by and/or build.

My Question To You:

Has any of you attempted or constructed a project like this? What kind of technology are we looking at here and is it something that I, as a college student, could acquire the materials for and build? Do you suggest a project like this is worth building?

Thanks

If you can get the nixie tubes, yes. There are no viable substitutes, though.

Do you suggest a project like this is worth building?

Yes. Not my cup of tea, but learning is always good.
