Now that's some beautiful Glitch Art!

You can achieve similar on terra firma. Go way out to the boonies away from city light pollution. You'll be in nature with all of the critters that entails, but hopefully the flying types. Set up your camera to frame just the night sky. Set it for long exposure focused at infinity. Place a dim light source near the camera but out of frame. Black lights work wonderfully well. As the night progresses, all sorts of flying insects will swarm your camera rig at random heights. As they fly around during the exposure, you'll end up with a very similar look.

  In the fine article, all the trails have identical paths.

    i said "similar". besides, mine cost pennies compared to what the image in TFA cost. you get what you pay for. or, set up the same rig minus the light, and then give the rig a shake while the shutter is open. much less random in the streaks.

  I like your idea, I could do it right in my front yard, but what I like about the image in the article is the very nice proportions and exact repetitions of the curves and even the little dove-head figure, and the fact that it was entirely unintentional. Added bonus that it cost millions and millions and involved over the top equipment and time and distance!

    >I could do it right in my front yard Great! I'm coming over next week with all my gear! Closest place for me is 4 hours away. It is my motivating factor of trying to buy a car again.

You can actually do useful astrophotography by slightly mis-focusing an SLR and wobbling it around. Each bright star will leave a trail, changing in brightness and color as the atmosphere twinkles.

That's an APOD candidate for sure! https://apod.nasa.gov/apod/ https://apod.nasa.gov/apod/
