I made what I would consider a placeholder logo for the site up there in the top-left. It’s the tuning curves from the NEF summary in the Nengo paper and I’ve gotten a bit of positive feedback on it (and it’s got a sufficiently good story behind it) but there are some things that bug me about it, and I don’t think it’s recognizable enough when shrunk down to a small size (16 or 32 px high, as is often required). So, I whipped up a slightly “bolder” version of it, with some variants.
Which of the below do people like the look of? We can certainly use different ones in different places, but it would be good to choose a canonical logo. If anyone wants to see variations of these (thicker / thinner lines, different colors, more or fewer tuning curves, etc) suggest them here and I’ll make them!
My vote would be the “6 curves all blue”. I also like the “6 curves coloured”, but the bottom line looks kind of awkward to me with the mix of overlapping colours. We could perhaps change that to just a black line, but I think my vote would still be for the all blue (although not a strong preference).
Hmm, I mostly like the 6-line all-blue one, but it is very close to an upside-down pentagram… In fact, now that I’ve noticed the pentagram interpretation it’s very difficult to un-see it… I’d also want the lines to be a bit thicker in the 16x16 version. And I think I like not having the bottom line at all (which might help with the pentagram visual…).
I think I’d lean more towards the brain-image that we’re currently using as the favicon for both forum.nengo.ca and for the nengo_gui. I think we should be using the same icon for both, but we should have a colour difference between the nengo_gui one and the webpage one (and maybe even the forum one). This is mostly because I often find myself with multiple tabs open and have trouble finding which tab is nengo_gui and which one is a documentation tab…
So I’d like an icon that we can have different colours for (or at least different versions for nengo_gui and the website). I’m leaning towards the brain, but I could definitely also see the tuning curves working…
Different colors for different things sounds good to me too! We could use the multicolored one for the ecosystem as a whole perhaps? In which case I’ll think more about choosing colors as each color should be a reasonable color for a project.
I hadn’t thought about the pentagram-esque nature of the 6 lines… we could switch to 4 or 8 lines is that would help?
Anyhoo, here are some of the other possibilities mentioned above for consideration. In all of the below, I made the lines a bit thicker, though I think they could go even thicker… Also I think the N made with tuning curves turned out alright! Though again, thicker lines might be better?
The brain icon is harder to play around with as I can’t find the original source of it… the .ico isn’t sufficient as the logo can’t only look good at 32 pixels. I’ll hunt around for that art a bit after I post this.
I think coloured project logos and multicoloured ecosystem would be awesome… I think I like no axis better.
Also Wondering if there is a good way to sort of embed the ‘N’ within more tuning curves, i.e. have the multicoloured tuning curves and have and ‘N’ coloured black within that? might be more effort than it’s worth though.
Nope, I don’t think there’s an SVG version of the brain. I made that favicon 16x16 version ages ago from the standard brain image we’ve used for the CTN logo and the Spaun videos, cropped, shrunk, and colour-inverted. I’ve got it as a 1600x1200 PNG, if that’d help…
I dunno, I feel like like those kinds of details (i.e., that the N is formed by tuning curves) are just nice bonuses; the main goal is to be recognizable and unique. E.g., there’s a brain in the ABR logo, but it isn’t front and center, just a nice detail. In a similar vein, my main worry with the brain logo is that it’s not recognizable / unique. There are lots of things that use a stylized brain as a logo so it doesn’t really scream “Nengo” to me.
Looking at it again, I wonder if the N logo is too close to the NY Yankee’s N? It looked kind of familiar when I was making it but I couldn’t place it. I kind of like the idea behind it, but given that similarity I think right now I’m leaning toward the 6 curves with no axis.
Is there any chance that we want to use the logo in black and white print-outs?
In general I would vote for simplicity, i.e. tuning curve logo > brain. One of the colored six curver versions would be my favourite at the moment, but too me it looks too much like a jester hat right now (though I don’t see the pentagram).
I like the idea of making an N out of tuning curves, but the current version looks weird to me. I have another idea how that could be done and will post it later once I manage to put it together.
