While The Mary Sue didn't post up pictures of their readers' costumes throughout October like we did, they did still do a round up at the end of the month. While there are plenty of great ones in their collection, this take on Microsoft's dreaded "blue screen of death" is a great example of how to turn a concept into a tangible costume. I particularly love Rachel's use of Perler beads as the Windows logo hair piece -and her blue hair only helps sell the costume.
Beth's Totoro dress is also quite cute and something that she could wear throughout the year, if she's nerdy enough.
