aevaI made a neat terminal-friendly cross hatching effect with unicode
Miss Aemilia🎀@aeva Now make an interactive mandlebrot with this.
Not even kidding, that'd be so cool.
@MissAemilia I don't have the spoons for that sorry
@MissAemilia if you want to give it a go, here's the relevant python function:

@aeva
Oooh, its been all too long since I made a mandelbrot. Maybe I should.

@MissAemilia I made a shadertoy version of the filter btw https://www.shadertoy.com/view/4f2fDc
demofox@aeva @MissAemilia there's a blue noise texture on shadertoy if you find it handy. It's the one that looks like a flat grey texture in the thumbnail. Funny enough, the low pass filter before shrinking the image to avoid anti aliasing removes the high frequencies, leaving nothing left :)
@demofox @MissAemilia whats this about a lowpass filter
@aeva @MissAemilia oh, if you shrink an image, it can't represent as fine details (high frequencies) so you have to blur (low pass filter) those details away before you shrink the image. Otherwise you'll get aliasing.
That's what's done when shrinking images, like for thumbnails.
Since blue noise is all high frequencies, when the low pass filter hits it, those high frequencies go away, leaving a flat grey image.
It's kind of comical.

@demofox @MissAemilia oooooooooh I thought you were remarking on the quantizing step in my shader, not why the thumbnail is gray XD
that's neat, I had no idea that was why that happened
@aeva @MissAemilia oh OK cool. No, your work is primo and super cool.
@demofox @MissAemilia <3 btw I added some blue noise to the quantized variation (see the defines)
