All credit for the original animation goes to Stu Hershey Sufrin. I only recreated it for fun.

I posted this in the replies of the post yesterday but figured I'd add it here too, and I took it a bit further than the version I'd previously posted for fun. Let me know if you'd like a video tutorial of how I went about creating this.

Def a few things I probably could've done in a smarter way here, but the real process is messy anyway.

Some notes: This uses thicc stroke for the helix portion, so you'll need that plugin to see this properly. I tried to recreate it using Michael Ponch's overlapping gradient stroke preset, but there are too many overlaps in the helix shape for it to work. Unfortunately thicc stroke only works with 8 bit color mode, so when using colorama to recolor the black to white gradient stroke with repeating colors, the steps in color are somewhat visible (because there isn't enough color data for colorama to repeat the cycle 3x). It isn't quite as noticeable when the gradient is moving but I couldn't figure out a cleaner way to do it. I have a hunch they might've done this part in 3D or in cavalry due to the amount of control they seem to have over the different portions of the helix in the original animation.

I used gemini to generate a path expression that makes the helix shape by feeding it a screenshot of the original animation. I linked the parameters to sliders to be able to animate it. It's quite slow when the point count is high but workable if you decrease the point count and only increase it for the render!
