Since JuliaCon and its avalanche of stickers are upon us, I thought it would be nice to give [JuliaDiff](https://github.com/JuliaDiff) a logo. We have one on GitHub but it’s old and not really differentiation-specific. I gave it a try with Luxor.jl, but I’m a bit of a newbie, so I would really like to know what people on here think… especially @cormullion 😉  
Feel free to play around with the code and suggest alternatives!

I find the existing logo very cool:  
 ![](https://global.discourse-cdn.com/julialang/original/3X/a/2/a2a3f5439cbf3addfd12c659508590c9971e3022.png)  
In my opinion, taking the isolines could be a good starting point for making it something vector-like. But I can’t allocate time to explore that further. Perhaps someone else feels the same and can explore this.

A rounder, friendlier version that reuses the font from the Julia logo

Cool stuff! I love the direction.

The issue with the current logo isn’t so much that it’s not very literal - logos aren’t illustrations and don’t have to be literal - it’s just that it’s a bit untidy. Oddly cropped, peculiar colors, and looks a bit like the rear lights of the car in front of you in the rain. If it could be simpler, vectorised, drawn with more detail - perhaps it could be refreshed…

The triangle shape in your sketches is great - I don’t think it’s been overused in the Julia ecosystem, and I think it could be a strong component of a good logo. Lots of potential for exploration I think:

I’d also suggest trying some ideas without the blends - blends are cool, but don’t always reproduce well on stickers and t-shirts, or at low resolutions…

Maybe you can get the asymmetrical look (with the walking stick) working well… I’m not sure the “f” is saying anything to me, but perhaps you’re tapping in to some maths vibes that I wouldn’t be aware of. 😂

Thanks so much for taking an interest and making some propositions! I love the Escher vibes of your take

Just for context in case some people had missed it: this triangle shape is the [`\nabla` operator \nabla](https://en.wikipedia.org/wiki/Del), which is used in math to denote the gradient of a function. In other words, \nabla f(x) is the gradient of the function f at the point x, aka the direction of largest slope. Hence the connection with JuliaDiff, whose main purpose is taking derivatives.

would you mind sharing the source code?

Your graphics are always fascinating and it would be cool to see how you make them 😃

With that shape and that blue color, the `f` really looks like facebook’s. Maybe a f instead would look better?

Yes, no problem - although there’s no maths constructions here, I wasn’t sure how to make it geometrically … 🙂

What about a very slightly blended version of @cormullion’s logo, to boost the 3D feel?

LOVE the impossible triangle type \nabla above!!

Why not use a Jj instead of Ff to emphasize julia?

I see that:

>
> A relativistic Julia gradient: [JuliaDiff\_relativistic\_gradient\_animation]

uses j and the rmgb dots, which is way cool!

Start with \delta j or \nabla J ?

\delta julia  
julia \delta  
julia\_\delta  
\delta ulia

\nabla Julia  
Julia \Delta

\nabla J or any of the variants (with J not spelled out as Julia) looks like we are differentiating a Jacobian J and not a function f.

Since the nabla symbol and the Julia logo are both triangles (pointing in opposite directions) I think you could get something cool by juxtaposing them somehow.

e.g. you could put them side by side to make a parallelogram

e.g. you could overlay them to make a six pointed star

(On phone can’t demonstrate)

If we do this we’ll lose the meaning of \nabla, which should be a vertical triangle. Alternately we have to put the three dots on top and get a diamond?

I think this has religious connotations that we want to avoid in a logo?

I just meant something simple like this - but you know, fancier, with shadows and lens flare and not done in paint

I quite like this because it means “the derivative of Julia” - when many of the packages are precisely for taking derivatives of Julia code.
