Jim Bumgardner, Flickr master and blogger at Krazydad, has made an avocation out of creating what he calls "coverpops." They're collages of hundreds, even thousands, of book and DVD covers that form beautiful patterns – and each individual title pops up when you mouse over it. His masterpiece is undoubtedly the coverpop of thousands of science fiction and fantasy magazine covers from the late 1920s through the present. The magazines create a rich, rainbow-hued collage, and the covers themselves make almost universally fun gawking. Space aliens, babes in distress, and big phallic missiles!
Jim writes:
Playing with this coverpop is like crack for anyone who is intrigued by vintage magazines or science fiction history. You can even drill down to the Visco archive for more information about each title. This is truly a digital archivist's dream: data displayed in a way that is both aesthetically pleasing and informative.
