First we had laser engraved sneakers from Nike... then some folk got imaginative and got their powerbooks and other tech engraved. Unbelievably cool but not accessible to folk like me.
These moleskines from www.engraveyourbook.com are fantastic and accessible (although the international postage is the same as an engraved moleskine). You can choose their fab designs like the one above... or upload your own artwork for $5 more. They engrave the spine too which is extremely useful for an obsessive like me. Check them out.
