Martha Stewart weddings featured this very creative idea in the Winter 2010 Anniversary Issue. I love the idea! Here is the description from the website below:
Strips of a Lifetime! Having a photo booth for your guests is a fun, interactive alternative to a traditional guest book. To keep that playful and conversation-starting spirit going long after the event, frame the strips and display them on your walls. Most people hide them away between the covers of an album, but why do that when a cinematic collage like this is an instant touchstone -- a reminder of who was there to witness your vows -- not to mention a visual wow. What you'll need for the project: card stock that fits your frame, along with 20 to 30 photo strips per collage. Be sure to take your time deciding what order they should go in; you could place them randomly or divide them into friends and relatives, for example. Once you've got everyone just where you want them, arrange the strips so they overlap slightly, and mount using archival double-stick tape, securing one strip at a time, starting from the left side. 11 3/4-by-34 3/4-inch "Ribba" frames, each $20, Ikea. "Sussex" sideboard, $3,550, The Conran Shop.
