***Run in TurboWarp*** https://turbowarp.org/1290806683?hqpen Press space to toggle between low and high resolution, high resolution is only smooth on TurboWarp or if you have a really good computer. Press e to switch between a swirl effect and a wave effect, press b to switch the image.
This works by modifying the position of each of the pixels on the image, making whatever pattern you put in. The blurry effect is made by making the pen transparent so it shows some of the previous frames underneath. The images come from the Scratch library and were scanned with https://scratch.mit.edu/projects/804193901/ This was inspired by https://scratch.mit.edu/projects/55315592, it's basically the same thing achieved in a different way.
