Halloween is one of the best geek holidays of all, and to celebrate we’re collecting some of the most fun and unusual costumes today. Send us your favorites with a short description to john@geekwire.com and we’ll post in our gallery if it’s suitable for our geek audience.

Here’s a look at some of the photos we’ve compiled so far, but I know there’s more.
