Similar animated: d/2108 by u/mxfh , year 2017. I was trying to remix that but it was difficult so I came up with another idea to prevent the display of lines from behind that should remain hidden... I'll post as a remix sequence...

The original image was created by "intriguing series of pulsar charts". Here is the original Ph.D. dissertation page where this were published more than 50 years ago: https://twitter.com/ChristiansenJen/status/1…

Someone on Twitter sent me an interesting page about javascript implementation of this code: https://maxhalford.github.io/blog/unknown-pl… so I added the code here (my js.do platform) to be viewed and remixed: https://js.do/rsiqueira/joydivision
