Recently I've been working on drawing the Firefox logo using Asymptote, and just recently with a lot of help from sonone we finished it!

Inspiration
I decided to draw the Firefox logo after seeing sonone's submission for the Asymptote Design Comptetion. Two of their submissions were Asymptote drawings of the browsers Safari and Chrome and since Firefox wasn't there I decided to draw it. :)
Beginnings
I drew the logo by copying a 128x128 Firefox logo into MS paint and finding the coordinates of each intersection to make the curves.
This resulted in the below image.
![[asy] //firefox fill(Circle((64,64),30), purple); //fox belly draw((76,82)..(66,38)..(35,66)); path a = (76,82)..(66,38)..(35,66); //fox lower mouth draw((35,66)..(27,69)..(23,75)); path b = (35,66)..(27,69)..(23,75); //fox upper mouth draw((23,75)..(32,79)..(44,76)); path c = (23,75)..(32,79)..(44,76); //fox middle nose draw((44,76)..(54,74)..(63,75)); path d = (44,76)..(54,74)..(63,75); //fill(a--b--c--d--cycle); //fox upper nose draw((63,75)..(53,79.5)..(46,84)..(41,89)..(32,92)); path e = (63,75)..(53,79.5)..(46,84)..(41,89)..(32,92); //fox left ear draw((32,92)..(29,99)..(29,106)); path f = (32,92)..(29,99)..(29,106); //fox left back draw((29,106)..(14,38)..(64,9)); path g = (29,106)..(14,38)..(64,9); //fox right back draw((64,9)..(113,35)..(105,100)); path h = (64,9)..(113,35)..(105,100); // fox outer part of inner tail draw((76,82)..(96,70)..(96,49)); path i = (76,82)..(96,70)..(96,49); // fox upper belly draw((39,59)..(63,38)..(96,49)..(111,81)); path j = (39,59)..(63,38)..(96,49)..(111,81); // fox middle belly draw((111,81)..(108,92)..(105,100)); path k = (111,81)..(108,92)..(105,100); // fox lower chin draw((39,59)..(45,67)..(58,70)); path l = (39,59)..(45,67)..(58,70); // fox snout draw((58,70)..(60,71)..(63,75)); path m = (58,70)..(60,71)..(63,75); //fox outer right ear draw((32,92)..(37,98)..(45,102)); path n = (32,92)..(37,98)..(45,102); //fox inner right ear draw((45,102)..(44,95)..(46,84)); path o = (45,102)..(44,95)..(46,84); // fox middle belly draw((8,64)..(39,17)..(111,81)..(102,98)..(95,106)..(87,115)..(81,124)); path p = (8,64)..(39,17)..(111,81)..(102,98)..(95,106)..(87,115)..(81,124); // fox upper left tail draw((81,124)..(68,112)..(62,94)); path q = (81,124)..(68,112)..(62,94); //fill(c--d--e--f--g--cycle, orange); shipout(bbox(lightgrey+3mm,FillDraw(lightgrey))); [/asy]](http://latex.artofproblemsolving.com/b/0/1/b018cf6aa2eff1ce6f9c685efcc52349f7b95eca.png)
But then I encountered a small problem, I had no idea how to paint it!
Continuation
So that's when I asked sonone to help me color it. I found a nice function from here (which I later used to draw in inner circle). But sonone found a better function to help us and they also fixed the curves up a bit. They then drew a part of the fox using that function.

Then I learned how to use this function, I fixed the colors of the image above and colored the rest of the image!
Here is the final drawing:
