Take a guess at what you're looking at.
No, it's not the moon and no, it's not some 4th grader's attempt to recreate the Grand Canyon, in miniature, via elaborate sand sculpture. Here we have a photograph of one single groove of a vinyl record (remember those?) magnified 1000 times. Beautiful, no? Feast your eyes on a few other close-up shots of records, at various magnification, including one in 3-D. (if you have some glasses laying around.)
