Just to clarify: I don't want to make it an "official" logo or such thing. I am afraid that trying to do that would result in a lot of bikeshedding.

This is just a favicon that looks like a board (to me) and has a voxpupuli color that I propose to add for a purely practical reason: it's faster to find a tab in a browser if it has a distinctive icon instead of having to read the title.

can you please rebase against master so we get rid of the merge commit?

[gdubicki]

Sure, rebased.
