A Holiday Symbol For Atheists?

What could be better than a vacuum tube, a container which holds Nothingness, to symbolize the fact that we are all just atoms in the fucking Void?

And now that we have our symbol, we can protest if City Hall doesn't display it prominently, alongside their Xmas tree and their Menorah and their Bodhi Day meditation mats and that little shrine where Pogo Islanders can pray to their magic banana.
