Spotted in the wild: a cybertruck painted rust-colored. Well, that's a time-saver, I guess.

@bit101 yep. So neatly applied to the side panels...

Again for people (racists), complaining about falling birth rates:

The birth rate for women over 40 is not falling. The birth rate for women over 30 is not falling.

What's happening, is girls 15 to 17 are having fewer babies. Kids are having fewer kids.

Also, this is an interesting way of saying that "Teen pregnancy is down, due to sex education and contraception."

In 1991 25% of 15 year olds gave birth before they turned 21. That's bad. Now it's 6%. That's better.

@mekkaokereke @Jennifer

Read an article about a poll. Headline: most American men think Trump respects women and vast majority of Republican men think so

I snorted my coffee, no lie

Well, if that is respect, it is any wonder women aren't interested in those guys?

Triangulation experiments

Stupid simple:
Draw a curve from hither to yon
Draw another curve from hither-ish to yon-ish
Interpolate N points on each curve
Draw a chain of triangles
Colour

Interpolate additional paths in between and triangulate between each of them

Bit of a quilted look

Someone smarter that me could figure out how to set stroke widths and opacities to smooth this out perhaps

mathling, 24 days ago

With Delaunay triangulation

Which has now sent me down a rabbithole of reimplementing my Delaunay implementation because it is slower than I'd like and I want to avoid those cross-gap triangles as well

(Edit: add alt)

Supernova remnant

Noise + sheets of translucent triangular faces + perspective

Here I'm using a billowy fractal noise function, which creates the jagged appearance

Applying a sinc curve to fractal billow output

The magnificent bathymetry gradient, always good for mystery and wonder

Achievement unlocked: I can now make all the Archimedean solids

Here's a nice little snub dodecahedron

Gotta say, most of the Platonic solids are boring, but these are pretty nice

(Must not look at Catalan solid page, must not look at Catalan solid page...)

More fun with curve ribbons

Rose curves

#XQuery #SVG #CreativeCoding

A wobbly translucent rose in yellows and greens. There is top-bottom symmetry, but it is like a rose seen through rippled water: the loops wobble and bend before looping back to the center.

Starr roses

A translucent ribbon loop curling over itself in five places. There is a kind of pseudo-symmetry: you could almost tell yourself it is radially symmetric if you looked at it from the right angle, but no, it is not. Earth tone colouring with distinct bands of blue and yellow-green. It says spring to me, somehow.

Random polynomial spirals

A twisting S shaped translucent white ribbon, ending is a fantasmagoria of curls and loops at each end over a black background.

mathling, 1 month ago

So many cool shapes, so little time, what shall I try next? What?

mathling, 1 month ago

@jimfuller hmm... solids... hmmm

mathling, 1 month ago (edited 1 month ago)

@ndw @jimfuller yeah, that he is

The thing about solids is, well, they are three dimensional: since the algorithm wants to map to corresponding points horizontally were have a wee problem. To pre-project or not to pre-project, that is the question

mathling, 1 month ago

@jimfuller Curse you Mr. Fuller! You have successfully nerdsniped me, and now I am lost, oh so very lost, in a thicket of Archimedean solids

Thin-film knots

Because anything you can do with mangled circles and meanders, you can certainly do with a modulated torus knot
