Today started out beautifully! A little shower with some sun and voila! Rainbow! And then, 12 hours later... snow storm! Just perfect! :)

The rainbow photo is stitched out of 3 8MP photos using open-source tools HuginOSX, autopano-sift and enblend. They produced a 93MB TIF file, which I cropped and saved to a 8MB JPEG ( 7191x2632px with 150dpi ). My poor PowerBook almost died! :(
