During the process of the new gtk+ website, we thought it was time to do away with the old logo. Although it have served it’s purpose well for many years, it was time to make something that was a bit more pleasant on the eyes and was possible to scale, use in print and web etc.
I’ve set up a wiki page on GNOME live where you can find it in svg, eps and png-format. Please add any other formats you think would be usable. I’m planning on putting up a black & white version for mediums where few colors are needed soon.
Someone pointed out it resembled the logo of Kristallen, Sweden Television Award a bit. I’ve never seen that event before, so any kind of inspiration is totally unintentional. I guess there is a certain limit to what you can do with a stylized cube. 
It’s time for you to confess, my friend: it was you who secretly requested Inkscape’s 3D box tool GSoC project
Cubes in logos? Why I never!

Congratulation
I like the old one better. Isn’t it possible to make a nice .svg of the old logo so you can still do rescale and things like that? I think the old one is a lot more recognizable…
Anyway, the new website is cool
It looked odd to me, so I took a closer look. The edges are not parallel, so it’s not a technical perspective. But they also have no common vanishing point (per direction, that would make 3, or 2 with vertical upright edges.
Thorsten: I tried to use a more realistic view in the process, but it turned out looking totally boring. The final version turned out slightly more playful.
( that said, Im no expert on perspective, so if you have some modifications that might work better, feel free to submit )
Lucky: I actually have a version of the sketch logo on my hard drive, but I fear it might be weird if we have several versions of the logo popping up here and there. Bug me harder and I might give it to you after some pressure though
Nice one Andreas
