Marching lines

Horizon

This is essentially the exact same code as Stay Upright; the only real difference is that it's viewed from a different perspective.

Here's the code:

DynamicModule[{n = 100, a = π/4, viewpoint = {1, -1, 0}, θ = π, range = 8, plane,
  cols = RGBColor /@ {"#F71735", "#FDFFFC", "#41EAD4", "#011627"}},
 plane = NullSpace[{viewpoint}];
 Manipulate[
  Graphics[{Thickness[.003], 
    Table[{Blend[cols[[;; -2]], r/π], 
      InfiniteLine[
       RotationMatrix[θ].plane.# & /@ {{Cot[r] Csc[a], 0, Cot[a]}, {0, Cot[r] Sec[a], -Tan[a]}}]}, 
      {r, 2 π/n + s, π, 2 π/n}]},
   Background -> cols[[-1]], PlotRange -> range, ImageSize -> 540],
  {s, 0, 2 π/n}]
 ]

@Clayton I've read this on your Facebook, congrats!

My animation "Horizon" will be one of the featured GIFs in the ello.co x MediaLive: International GIF Competition at MediaLive next week at the Boulder Museum Of Contemporary Art. MediaLive events are free and the GIFs are on display all week (May 15-21), so if you're in Boulder next week, go check it out. Incidentally, I plan to attend the opening reception on Monday, May 15, so keep an eye out for me if you're there.

Please feel free to post any photos or other materials from the exhibition if possible. Good luck and have fun there!

Thanks! I will try to remember to take a photo or two.

Here is a photo of part of the exhibition:

And also me with another display:

Sorry about the terrible lighting and my substandard photo editing.

Here's a short timelapse that Justin Gitlin made showing all the GIFs that are in the exhibit.
