The Surface Languages logo was nothing special. It was removed in a general refurb. of the site.
And I can't decide if I want a moon logo or something more language related. And so until that point it remains in limbo.
I added this page as one of my favourite sites has a similar (almost) hidden page describing their logo, and the page is described as an easter egg.
Whether of not that that is a fair description will depend on the number of visitors to this page, and FYI you are visitor (or should I say guest) number .
