I found this currently free application (thanks to blog favorite and fellow San Franciscan sfgirlbybay) Poladroid that turns any photo into a digital Polaroid. It’s super fun and makes normal, everyday shots into retro chic works of art. It’s also a fun app to use since a little camera lives on your desktop, prints the photo and you can shake the print with your mouse to make it develop faster. Just like the real thing, it’s slightly agonizing waiting for the final product. But hey, anticipation is part of the fun!
There’s also a flickr group, which I promptly joined. And one of it's members is working on a Blurb book already!
