Seeing and/or believing

My friend Peter just had some life-changing surgery.  The genetic lottery gifted him with cataracts as an infant that left him with compromised sight for most of his life.  Doctors repeatedly said that there was nothing they could do to correct the problem and he'd just have to accept the fact that he would always live in a world where everything he saw was two-dimensional.  Peter, my strong and brave friend, never took those doctors' words as gospel.  He recently had surgery that is allowing him to see in 3-D for the first time in his life and he's chronicling it in his blog Diving Into Depth.  His journey is fascinating and he tells his story very poetically.  Now, if you'll excuse me, I have to go find a bunch of cheesy lenticular postcards to send him.  Any leads would be appreciated!
