How about a logo?

Proposed logo included.

Fixes #23

Looks great. Do the curves in the background have any significance, or are they just random sin functions?

[jacobwilliams]

haha! They are totally random! I committed the svg file so we can make whatever changes we want if necessary.

We shouldn't overuse the “white on violet with capital letters in a box” for all logos in the Fortran ecosystem. If you have a look on logos in the Python or Julia ecosystem you find that they either connect by color (blue/yellow for Python, purple/red/green for Julia, ...) or by shape (Snake for Python, three dots for Julia, ...) to the language. For Fortran our colors would be white/violet and our shape would be capital letters in a box (we could sharpen this a bit), having both seem redundant.

I think it is better to focus on FFT / waves / ... rather than the fact that our implementation is in Fortran for the logo.

I'm not too fond of using the same font as in the Fortran logo (from the old IBM manual) for all packages. It's okay for the language itself, because it gives a feeling of maturity. But when you have multiple letters it looks kind of old-fashioned. For a FFT package, I almost expect to see a sans serif/italic font. The slanted letters give a sense of speed. The FFTW logo is a prime example (maybe that's where my expectations arise from).

Maybe a variation on the proposed logo for fpm would be a better fit. With FFT I also like to picture the "green" signals like you'd see on an old cathode ray oscilloscope.

Hopefully this 1-min attempt in gimp conveys what I'm trying to communicate better:

@awvwgk let's write down the guidelines. I agree that we should be careful and not overuse the Fortran's logo design. Do you think these are ok:

• The same font F, but change the colors, and add something, such as the LFortran logo: https://gitlab.com/lfortran/lfortran (we need to put it on our front page...)
• The same purple/white colors, but change the font, such as the fpm logo: Logo for the Fortran Package Manager fpm#380 (we need to just choose and be done with it!)

I'm OK with whatever! I made the one I submitted very quickly.

I'm OK with using the purple in some way as a reminder that it's in Fortran. I think that is nice way to give some visual consistency to the ecosystem. But I agree they don't all have to look the same, and if somebody comes up with something better I'm OK with that too.

Making logos isn't usually high on the priority list of people writing Fortran libraries. I've cranked out a bunch for my projects. I think it does add an air of legitimacy to a project to have a logo. :)

@jacobwilliams You should close this PR. A new PR (#40) has been made with the logo files created by @1984logo.
