Flickr Mashups

I am happy for the people out there that are computer-savvy enough to meld two websites together to create their own mashups. That would take a lot of imagination (and possibly boredom). “Hmm.. if only I could combine the pictures from Flickr with a map from Google..” I am not quite sure the usefulness of any of these mashup besides being fun to look at. I liked the colors in Color Pickr.
