If you ever have eight or ten hours to kill, check out CoverPop.com, a new mashup site and a goldmine of found history. According to the site’s operators,
Each coverpop is an interactive mosaic, made of tiny images, such as magazine covers. These are called “micro thumbnails”. As you drag the mouse over each micro thumbnail, it pops up to a full-sized thumbnail image, and provides some information about the item. For some coverpops, you can click again to produce either a full-sized image, or to go to another website to learn more information about the item.
Each time you arrive at the site or click on “more coverpops” at the top right corner of the screen, CoverPop will present you with a new, randomly selected mosaic. For example, when I first arrived I was shown CoverPop’s collection of “a few thousand science fiction magazines”.
Other historical collections include vintage pulp fiction covers, Mad magazines, old cereal boxes, and (remarkably) engravings from the works of 17th Century Jesuit practical mathematician and natural philosopher Athanasius Kircher.
