This image (called a texture in-world) is being used in Second Life at the moment, obviously created for last year’s NaNoWriMo writing marathon. I’m afraid that I can’t find who should be credited for it. The conversion from tga to jpg has muddied the image a little, also, but you get the gist.
There are similar coffee and otherwise inspired NaNo calendars, desktops, and stickers from previous years found at the links below. 2011 and 2012 links include stickers for laptops and facebook covers. Search on google or your procrastination engine of choice, and you’ll find many bloggers sharing their own creations also.
