I'm always looking for something new that can help photographers. PosterBrain.com is something that I can see a use for. A lot of times, I look at posters and think that I'd rather have one of my train shots or a Black and White photo that I took as a poster.
PosterBrain.com allows you to choose a photo and have it made into a great quality poster.. and even get it delivered the next day. I'm not sure I need the next-day delivery.. but the concept is great. Check them out.
