WeAre-APOD is a small program I developed since APOD (Astronomy Picture of the Day) has so many nice images every day and I couldn't find an available program to use (except a small and very nice utility for PocketPC). Therefore, I developed my own - in less than one day - so please spare me of any criticism regarding lack of documentation or trivial use of programming.
