Sweet Lord! This is amazing! Over at Coverpop you can turn any Flickr set into an amazing mosaic where each image of potentially thousands can be viewed by simply hovering your mouse over the picture. My Vintage Mini-Skirts group has nearly 1,500 pictures in it, and they're all visible in one titanic collage.
View the vintage miniskirt collage here and maybe even make one of your own. If you do, please let me know so I can check out your creation!
