What's more fun than a Dalek Christmas tree? A gift guide that doubles as a giveaway.

From Darth Vader cufflinks to nerdy books, any of these eight unusual gifts would be great for the geek who has everything — and you can enter to win any of them right here.

Here's how it works: To qualify for the giveaway, enter a comment stating which gift you would most like to receive and why. Deadline to enter is 12:01 a.m. Pacific on Dec. 16, 2011. Randomly selected winners (one winner per item) will be notified by e-mail or Twitter. Winners must live in the United States.

Note: If you do not have an e-mail address or Twitter handle associated with your Disqus login, you must include contact information in your comment to be eligible. Any winner who does not respond to Wired’s notification within 72 hours will forfeit the prize.
