Everytime I wander through art galleries and gaze at the portraits I always think about how amazing it is that they've lasted the test of time. I bet they didn't think they'd be hanging up for all to see when that sat for it! I've always fancied the idea of one of me (after all, in a hundred years it could be anywhere), but perhaps this is a much cooler, less stuffy way to go.
Ermadid on Etsy is a pretty cool chick and for only $100, you can e-mail a high res photo of yourself and two weeks later you get a cute, quirky portrait. If you're stuck for a present idea it would be perfect =)
