It's pretty much exactly the same as my day to day writing set up, with one crucial difference: my lucky red NaNo coffee mug. Oh, and the Comfy Chair has not yet been rolled out of the office into the dining room.
On the right is my basket-o-crap with books, gum, a little BPAL Polyhymnia to inspire, and my Big Notebook of Doom that has family trees, word count goals, etc. On the left is my Ganesh and my Zena Moon candle for writing.
In the middle of course is my crappy little Dell Inspiron 700m. I got it a few years ago because I liked how light and small it is. It's been a good computer overall, just so. damn. small. The goal for next year's NaNo is to have a new laptop.
So. What does your writing area look like? How do you get geared up for doing NaNo (or writing in general) - what are your superstitions and quirks? I must have both chai and cocoa/coffee, and I must have Extra cool watermelon gum. If I don't chew gum, I end up snacking, and that way lies disaster.
