This weekend I was playing a bit with displacement filters, with the help of https://www.smashingmagazine.com/2021/09/deep-dive-wonderful-world-svg-displacement-filtering/
It's actually not that hard to get some cool effects from this. However, it's a bit of a shame that nice distortions require some big gaussian blur kernel... I need to see if I can get similar effects by precomputing the blured images and just blending them with transparency.
