What is your process for making these? incredible
u/taupelink

thank you! lots and lots of trial and error, lately aided by https://capjs.3d2k.com/ I keep playing around with variations, e.g.: for the Y-coordinate, k+i*Y,k-i*Y,k+i/Y,k-i/Y each have a different effect
u/taupelink

for those unfamiliar with dwitter-style compact JS code: for a typical dweet of this type, each frame draws a bunch of rectangles. each rectangle has random coordinates for its upper left-hand corner. the RGBA (color and opacity) of the rectangle depends on those coordinates and on some other parameter that gets modified with each step. The dimensions of the rectangles shrink over time, thus adding finer-grained detail
