My wife asked if I could make something like this photo (but a little different) so we could print it up and put it up in our house.... Um ... YES I CAN! #mathart 
(what I have after a bit of hacking around) 
Plus, any project that naturally uses phi is awesome! 
(why did I name it fib? Who knows, just changed it to phi and phiAngle)
Here’s the gif of this version:
.@mpershan The spacing is the battle. Here’s another approach using 34 log spirals (desmos: desmos.com/calculator/nvf… ) with 55 seeds evenly dispersed along each spiral. 
if you fiddle with the circle size then you get this, which is totally not the same as the original: 
Thanks to @_kcnarf who recognized the original image as a Phyllotaxis arragement (easy to implement too!) Here's a gif: desmos.com/calculator/s2t… bl.ocks.org/mbostock/11463…
Yep, that's it! The colors are randomly coming from this photo from flickr (cc allowed) 
(flickr link: flickr.com/photos/amatuer… )
Here’s an improved version that grabs colors from a new source (a HDR sunset on the ocean photo) & gets rid of the super light colors. First uses fibonacci numbers 34 and 55, and the second is the phyllotaxis arrangement. #mathart 
And here’s a weird one that makes triangles out of the three closest points. 
And here is the fibonacci technique in desmos (tougher to do, requires a 2D list): desmos.com/calculator/dxh… 
Here's the voronoi version (distance capped out so the outside stays white) (thanks again for the inspiration Franck! ) 
Voronoi of the Fibonacci version of these sketches:
