Christmas is coming, the goose is getting fat, that big red suited anti-burglar is sizing up your chimney. But without decorations he may sleigh on by. And without suitably geeky decorations he might not know what sort of high tech kit to leave you.
Whether you're a Trekkie, a Game of Thrones fan or just a nerd with a passion for the periodic table, we've got something for you. Marvel at the Christmas joy, why not make your neighbours jealous with a lawn ornament or two? Or geek out your Christmas tree with nerdy lights and ornaments, there is bound to be something for everyone, well if you like geek things.

Weeping Angel tree topper
For the Dr Who fans out there, this Weeping Angel tree topper might be the perfect addition to the top of your tree. We're not too sure it's in keeping with the "Happy Holidays" spirit, but it's certainly nerdy!
Motherboard wrapping paper
This nerdy motherboard circuit wrapping paper looks more like an intricate circuit board blueprint than something you'd use to wrap up presents and we love it. A brilliant way to give geeky gifts this Christmas, even more so if you wrap up something geeky inside too.
Deadpool Funko POP! party lights
These officially licensed Deadpool string lights are a great addition to any Marvel themed Christmas but they'll fit right in with standard decorations too thanks to the red and white theme of Deadpool's mask.

These Totoro Spirit ornaments are the perfect geeky gift for any Anime fan and are inspired by the My Neighbor Totoro fantasy film. Customisable and hand-painted on shatterproof material too.
Santa’s Trek - Santa Star Trek stocking
If you've ever wondered how Santa manages to make it around the whole world delivering presents throughout Christmas before the kids stir, then this might well be the answer. Star Trek and jolly old Saint Nick have teamed up to deliver gifts at warp speed. Though we do feel that using the transporter to get presents down the chimney might well be cheating. We love this geeky stocking and the level of handcrafted detail on it is fantastic.

If you love Star Wars, then this is the must-have decoration from our list. Weak thermal exhaust port not included, so you don't need to worry about it blowing up. It does, however, include awesome lights, sounds and remote control too.
Gotta catch 'em all! Pokémon merchandise is everywhere and now they've even made it onto our Christmas trees. The Pokémon themed baubles come in sets of four and are a great way of showing off your inner Pokémon nerd. We wouldn't recommend throwing them though, because they're baubles and yes, they are breakable.
These officially-licensed Star Wars BB-8 droid lights can be hung on any nerds tree, wall or spacecraft cockpit this Christmas. A brilliantly bright set of lights to add a little nerd flair to your home this holiday season.
Star Trek 7-Inch Spock and Tribbles table centrepiece
Spock from Star Trek is a Vulcan. Emotional holidays like Christmas baffle him. That's captured perfectly in this Christmas decoration for the discerning geek.
