They say Halloween brings out the crazies, but it seems to be the time of year when geeks get their creative juices flowing as well. We’ve all seen Princess Leia and Superman costumes come out year after year, but it’s the original ones that make us take notice. Here’s some of the most impressively geeky Halloween costumes this October:

Most Authentic – Lego Vampire

Considering this one only took about a week to make, and 50 EUR, the detail is pretty impressive.

Most Original – Angry Birds

You know you’ve got a good product on your hands when people take it this far. Of course, Angry Birds isn’t the only mobile game to make it into Halloween costumes this year – Plants Vs Zombies got a look in, too.

Most Effort – Pacman and Ghosts

They even made the dots for Pacman to eat! Almost as impressive – a Mario Kart battle in progress.

Best Working Costume – Transforming Bumblebee

If I’ve ever seen an impressive costume, this is it.

Best Dad Joke – Pumpkin Pi

Most Geeky – Steve Jobs

Honorable Mention – Mii
