Just in time for our first big snow here in Boulder, Wired just published a set of beautiful micrographs of snowflakes, and as a bonus, some of them are in 3D!
Here is one of the 3D images. It’s a DIY 3D — let your eyes relax and blur, so that you’re slightly crossing them, and you see images. Then, focus on the middle image. It takes a bit of practice, but once you get it, you’ve got it, and it’s very neat.
Take a look at the related posts to see how to superglue a snowflake (keep it for posterity!), myths about snowflakes, and why snow squeaks when it’s cold.
