This will show you how to make a picture worth more than a thousand words (literally). I've always been a fan of large scale art that takes a collection of small objects to make a large image, and so in high school I created this self portrait using the text of Thoreau's "Walden".
Step 1: Picture
First, you're going to need a picture. Anything will work, but those with high contrast work the best. In highschool, I took pictures of my face with a light bulb right next to it to increase the amount of shadow.
I'm sick of my face, so lets use my roommate's.
