It's easy. Just manipulate an image of the instructables robot (http://www.instructables.com/files/orig/F6G/JR91/FNNKD7JV/F6GJR91FNNKD7JV.pdf) and mail it to:
Eric's Boring Wall
Instructables
489 Clementina St.
3rd Floor
San Francisco, CA 94103
Deadline is December fifth, it doesn't matter if you manipulate the image before or after you print it (or both), and you might get spotlighted. Not folding would be cool, but that is unnecessary. This seems like a great real world spamming opportunity with a low effort threshold.
This is everything I just said only it's straight from the horse's mouth. (http://www.instructables.com/community/Help_Decorate_Erics_Office/)
