I didn't have enough new bashes to fill out all 12 months, IMHO, but since I've been going nuts doing schematics of my bashes over the last few months, I decided to whip together "The 2013 Schematic Edition!" http://inpayne.com/calendar/kbcalendar2013.html Follow the directions to download. It's a 6 or 7 MB PDF.
I am impressed. The ships are all interesting and well-rendered. The attention to detail is wonderful. And the calendar is hilarious.
