Originally downloaded 11/28/06. Posterino aims to make "Life Posters" an every-household item. The concept still seems a little strange and narcissistic to me, but if I cogitate on it awhile, maybe I'll conclude that it's a better option than the walls of framed photos some people cover their walls with. 
Or, you could use Posterino to make Postcards, which is a more immediately appealing prospect to me. You can either email them, or have them printed through the iPhoto Kodak service. Posterino is in beta as I write this, and at $20 (now, $25 on release) it may seem a little pricey. Still, once we're all making Life Posters for everyone's birthdays, it might not seem like such an "occasional" thing.
Version as tested: 1.0 b7.
