Every year we celebrate Halloween on io9 by having a costume show on Flickr. Here you can see one of last year's costumes, Mr. and Mrs. Boba Fett, posted by Kristin D. Post your pictures in this year's io9 Halloween Costume Show!

Here's how to participate. Post pictures of yourself in our io9 Halloween Costume Show Flickr group. No, you cannot enter pictures which do not contain you. Yes, you have to join Flickr to post - sorry for the inconvenience - but you can log in with your Facebook or Google accounts. Every Friday until Halloween we'll post a few of the coolest, weirdest, and awesomest of the costumes here on io9. You can post pictures of yourself in costumes from Halloween past, or give us a peek at what you're planning for this year.

Another great costume from last year was the Hypnotoad, posted by Famous Potatoes. Can you do something better? Show us!

If you want to see more io9 Halloween Costume Shows of years gone by, here are 2010 and 2009.


So get on over to the 2011 costume show, and post those pictures!
