This animation was inspired by a 2018 TV show. Five awesomes if you can guess the name.

StarFox? ;)
u/joeytwiddle

Nope, sorry!

u/Purpzie

how the actual flip did you get 232 characters in there
u/KilledByAPixel

416 bytes, 140 characters ;)
u/tomxor

Or 140 unicode code-points (how the server evaluates length), 232 UTF16 chars (how JS in the browser evals length), and 198 effective bytes (134 chars provided by the escape compressor as 2 bytes per surrogate pair, and 60 bytes in the image manually packed into the string "o" with 20 bits per surrogate pair + 4 chars for variable assignment outside)... :) yay i'm learning about arcane UTF16 stuff.
