Let your geeky self shine this Halloween, but don't forget to include those around you in all the fun. If everyone in your group is fully embracing the holiday spirit, you might get more candy — and if none of you all can pass as age appropriate for trick-or-treating, you can at least have one heck of a party. So, with candy on the brain, we searched tirelessly to bring you and your friends or significant other or kids, dogs or turtles — yes, turtles! — the most fantastically geeked-out Halloween costumes to pop up recently. Up top is an instant favorite: Frankie the Unidentified Turtle Object (we've got a video of that after the jump). Down below in our gallery, you'll find 11 more ghouls and geeks. Bring on the festivities!

Iron Man is frequently paid tribute by skilled costume makers (exhibits A, B and C) — some who, like Mark Pearson, may have never known they had a little Stark in them. Maybe that's because, as Pearson says: "…I like the fact that he is not really a superhero, he is just a man with a flying suit… But what a suit — it's the Ferrari of superhero suits."

Going to a costume party is fun. Obsessing over the perfect costume isn't. Maybe that's why you usually decide what to wear late in the afternoon on October 31. To give you hand, we've slapped together some ideas that aren't too much work to put together. You won't win a best-dressed award, but you'll get credit for making some kind of effort. Plus, all these ideas appeal to geeks — perfect for keeping your friends guessing. So fret not — here are 12 easy, last-minute costumes from the world of tech, video games, science fiction and more that you could toss together after work today. (And no, neither zombies nor vampires on on this list. You can call that two free ideas right there.)

Halloween is a great excuse to eat too much candy and dress up like zombies, witches and ghosts. But for some people, it is also a chance to showcase their skills with handmade costumes that go above and beyond the call of costume duty. But there's another group of people beyond that. Those who take it a step further and really pull out all the stops, creating insane and gorgeous costumes that are faithful recreations of characters from movies, video games and comics. For them, costuming is a passionate hobby, one that keeps going all year long. Here we've made an informal top 10 of cosplay costumes that caught our eye for how finely they're made, or how creative they are. We've reached out to the designers of each to find out how they were put together.
