Here is the trading card mentioned previously. It seems I can't get both images in the same post.
Anyway, some of the other applications that I explored included Fastr (a game where you are shown a series of pictures and attempt to guess the tag), TagMan (played like the familiar game of Hangman), and Flickr Flash Puzzle Zone (make an online jigsaw puzzle from a photo). I made a puzzle of Rusty and Duke's picture on the trading card and thought I could include the html link to it, but that's not working.
These games were fun but I mainly see them as a way to waste time. I doubt that I will use them very often.
