Smooth Abs - p=sqrt(p*p+a)-b
I learned about this smooth-abs p=sqrt(p*p+a)-b at https://youtube.com/watch?t=1087 by Blackle Mori acording to @iquilezles it was introduced by the user omeometo at https://shadertoy.com/view/wljXzh
It's possible to make some really cool "soft fractals" using this technique! Awesome!
