Something I used to do when competing and an "altered image" was required. I called it - Out of Frame - for obvious reasons. If you're interested in the technique here's a "how-to" - http://www.pbase.com/ed_k/oofhowto and here's a gallery of these things from several years ago before I stopped doing them - http://www.pbase.com/ed_k/out_of_frame
When you print one of these up and mount it on a backboard for a competition you'd be surprised at how many judges get up out of their chair with a "What the???" and a closer look. Eight out of eight in my experience.
