All Messed Up: Unpredictable Graphics - Anna Gerber - 2004
Random World - Lawrence Zeegen

For this special commission, Zeegen kept an open Freehand document on his desktop while working on four other illustration commissions. Working 'blind', he placed, at random, invisible (white) images onto a white background over the course of one month. At the end of this set time period, he turned the background black, making the piece visible, to find that random elements from the four commissions had created a fifth piece.
