Playing with Flickr can make the hours fly away. Just uploading your favorite photos, adding tags, descriptions...whew! I really enjoyed playing with the mashups and third party Flickr tools. I experimented mostly with FD's Flickr Toys. I made a movie poster and a calendar. All those tools were really interesting but the one I liked the most was the calendar. I could really see myself using this one. I have some great vacation photos and this is a perfect way to use them and remember my fun times.
