That changes now!
First, though, I want to say that one of my favorite things about the internet today is how artists and creatives of various sorts have found interesting ways to collaborate with others, specifically: me and you and everyone commonplace. I went into great detail about my excitement (and involvement) with Foster Huntington's The Burning House, which was my first foray into these online (and free) collaborative efforts. When opportunities like this arise, I'm finding it impossible not to join the legions of others who want to be part of it.
This brings me to the Stardust Project by Sergio Albiac, who (to sum it up) created an imaging program that takes pictures submitted by internet users (those "commonplace" folk I mentioned above) and generates unique portraits using a mosaic-smattering of nebulae images taken from the Hubble. He'll provide you with three different portraits, and they'll also be posted with the thousands of others on his Flickr.
I honestly can't remember how I found out about this project (it was just over a month ago), but you can bet that it took me about .73 seconds to start hunting for a picture to submit.
For the record, finding an image for this was tough for me (*white whine*). I don't have a lot of simple front-facing ones where I'm not wearing sunglasses, or someone isn't in the image with me, or I don't look totally dreadful. Sergio's instructions say that (for the most part) you have only one shot at this, and what you get -- you get.
