I've been trying to track that top image down for ages. This faux bokeh was a big inspiration for a VR piece I made: https://andybak.net/gossamer

(By "faux" I just mean this isn't simulating optics to any great level of realism)

I knew it was by inconvergent but I didn't think of looking on Github for some reason.

My implementation was actually different - I based mine on the work of Keijiro Takahashi: https://github.com/keijiro/VfxBokeh

in the event that you haven't seen it: https://inconvergent.net/2019/colour-shift/

I hadn't spotted that. That's much more digestible (and this page also: https://inconvergent.net/2019/depth-of-field/ )

How do you feel about the recent explosion of interest in generative art? Rather bizarrely it seems that people seem to think it developed out of crypto/NFTs and are unaware that people were doing it before it became hitched to this dubious trend. Do you think it will become tainted by association or can it actually benefit from all this attention?

That's really beautiful, awesome work and explanation of how it was done!

For those inspired by this, they may also like context free art - https://www.contextfreeart.org

For example: https://www.contextfreeart.org/gallery/view.php?id=4223

  startshape lightning 
  
  shape lightning
  
  rule 20 {
      CIRCLE[r -60..60]
      lightning[y -1 s 0.99 r -10..10]
  }
  
  rule 1 {
      CIRCLE[r -60..60]
      lightning[y -1 s 0.5 r -50..-20]
      lightning[y -1 s 0.99 r -10..10]
  }
  
  rule 1 {
      CIRCLE[r -60..60]
      lightning[y -1 s 0.5 r 20..50]
      lightning[y -1 s 0.99 r -10..10]
  }

Beautiful, and in Common Lisp just makes it that much better for me. Thanks for sharing!

As a generative artist I love seeing what other people do. Sadly I am not conversant in CL so its difficult to understand.

the most interesting part (as far as i'm concerned. i have some bias here ...) is the stuff about manipulating the graph structure. the concept is described in the readme, and does not rely that heavily on CL knowledge. it's not that the method is new or anything, just that i think it's a neat way to think about it. if you are interested in the code at large, then, yeah .. this isn't a good intro to CL.

I'm curious if you have any thoughts on doing the art stuff full time. I also have a mathematics background, and I have been working towards getting into digital art (not just generative art). While I work in software engineering now, having a more explicitly "creative" job has always seemed interesting to me. It seems there's a place out there for stuff like this, getting to consult with things like movie production and other art installations, for example.

Awesome! Anyone seen an equivalent in Python?

pretty!

startshape lightning shape lightning rule 20 { CIRCLE[r -60..60] lightning[y -1 s 0.99 r -10..10] } rule 1 { CIRCLE[r -60..60] lightning[y -1 s 0.5 r -50..-20] lightning[y -1 s 0.99 r -10..10] } rule 1 { CIRCLE[r -60..60] lightning[y -1 s 0.5 r 20..50] lightning[y -1 s 0.99 r -10..10] }
