Everyone knows that geeks run the world. They are the scientific and mathematical and grammatical backbones of society, but also suppliers of countless video games, masters of special effects, insanely creative, and champions of logic. So this Halloween, let your inner geek out. There's no one more enviable than you!

A Spelling Bee

Nothing more geeky than a good costume pun! For the full effect, be prepared with a couple super complicated words to spell amid frantic buzzing.

Lakitu (the cloud) from Mario Kart

Want to be a Nintendo character but tired of seeing Marios, Luigis, and the occasional Princess Peach? Be Lakitu from Mario Kart! Totally recognizable, and you won't blend into the crowd. You could also have a stop light hung around your neck if you're not into carrying a prop all night.

A Periodic Element

Want to be geeky, but also want to dress a little sexy? You could be a periodic element! Gold, silver, and copper all make for fun metallic costumes. All you need is some metallic clothing, a periodic label, and body paint in your chosen color. This makes a great group costume!

A Rubik's Cube

A Rubik's Cube is cute and simple, but also pretty geeky. It would be very simple to make with a cardboard box and a stack of colored construction paper.

Steampunk Maiden

If you like getting waaaaaay too involved in your Halloween costume, consider dressing up in Steampunk style. A mix of industrial revolution technology and science fiction, Steampunk is sure to amaze.

Wonka Nerds Couples Costume

Being "Nerds" is a great couples costume, but would also be a fantastic costume for you and your best friend! Use colored wigs or temporary hair dye to make it fun from top to bottom.

A Floppy Disc

Another simplistic, yet very geeky costume--the floppy disc. You could also scare small children with it, since they'll have no idea what you are.

Whatever your geeky costume choice, make sure to have fun and be safe this Halloween!
