J&M's Weather Mappy
This is an idea I got from Issue 134 of Web Designer. It is a "Mashup" combining Google Maps, WeatherBug weather information and Flickr photos. The thought is that you zoom in on an area on the map. Then you click on it ( once ) and wait - yeah, it takes a bit of time sometimes. You will finally be presented with a marker 
. Clicking on the marker will give you some weather information, and ... after still some time ... the photo with the highest "interestingness".
Yeah, I know this is not all very fast, but hopefully a little fun ?
PS: If no image is found within the set search area ( too many answers will slow it down even more ), you will get the question "No photo found. Would you like to expand the search area?" Clicking YES will expand the search area for photos. Clicking NO will cancel the search, and you can place the marker somewhere else. Biggest chance for success is clicking in big cities ! Good Luck.
