I wasn’t sure where to put this so I put it in the Lounge.
@tachiko has made a brush based on a MyPaint brush stroke, here:
Using a mypaint tip gives krita brushes a mypaint feel
As part of that, they made a “weird thing” image for masked brush use.
I’ve tried that “weird thing” (both as it is and also inverted) as a Gradient Map brush tip.
I used Rotation controlled by Fuzzy Dab to avoid patterning and a wide spacing to avoid streaking.
Here are the results using some of @Rakurri’s gradients that can be found here:

It’s not ‘art’ but it’s glittery
