      twitter just loves to turn videos to mush, doesn't it?

        anyway, some technical details: this is Floyd-Steinberg dithering, implemented in Rust in WebAssembly. and then made interactive in a way that hopefully shows off some of the nice texture.

          i've always wanted to implement Floyd-Steinberg, and I find the way the error correction makes it shift & shimmer fascinating and beautiful. it also means that you can't do it on the GPU! so this was a fun excuse to write an image mangling algorithm that has to be on the CPU.

            which was a great excuse to try out a tech stack that is wobbly and new, like Bambi on the ice. but that also promises to make single threaded, compute-bound calculations in the browser faster.

              anyway, fun to make. so far? i might mess with it some more, but sharing it now makes that a fun new project rather than an old one dragging on :)

                  and there's some dead code for animating the dither as it comes in

                    just found this image quietly beautiful
