What is the Geek Tree? It's a Christmas tree with a speculative fiction theme. And what's speculative fiction? Speaking broadly, it's a uber-genre comprised of science fiction, fantasy and horror, though in the case of the Geek Tree, it's primarily sci-fi. The tree is re-built annually by Ken Newquist, Nuketown's editor. Questions, comments and suggestions about the Geek Tree can be sent to Ken via this form.
