Halloween's just around the corner and it's time to start stressing about what you'll be. Forget "hot librarian" (yawn) or "'80s rockstar" (stale): it's time to go geek.
To help you celebrate your nerdiness, we've put together ideas for geeky Halloween costumes -- with some help from our HuffPostTech readers. Check 'em out: they're cool, they're different, and some are even sexy.
Got a geeky costume you want to share? Show us!
