Here's an interesting thought – to display a photo, you don't necessarily need the whole photo. That is the jist of this crafty idea from Photojojo. You'll take a regular photo, cut circular shapes from it then organize those shapes onto a wood block (with Mod Podge). Image what you could do with a person's face? Or a pug's? The wheels are turning. Visit the link below to get the tutorial.
