Heads up! This blog post hasn't been updated in over 2 years. CodePen is an ever changing place, so if this post references features, you're probably better off checking the docs. Get in touch with support if you have further questions.
The cover of the Joy Division album "Unknown Pleasures" is an icon of early new wave. The rippling lines somehow feel both orderly and chaotic (like the music behind the cover). The image makes a great jumping off point for a Pen, and the CodePen community came up with mesmerizing variations on the theme.
Here are a few of my favorites!
Mark Adam Benzan's "Interactive Joy Division"
Jesse Wells' "Unknown Pleasures - SVG Line Animation"
Riley Shaw's "Joy Division Unknown Pleasures"
"Squiggly lines" by Gabi
There's a hidden meaning behind all those squiggly lines — the original image is a radio telescope's graph of pulses from the first pulsar discovered by humans. If you're up for a long-read, there's a great article about the image's origin by Adam Cap.
I've gathered these and more in my Unknown Pleasures collection, and I'm always keeping an eye out for more!
