Yes! That's what we should have had. I believe this is based off of the Ubuntu armel port, with open source apps taken from maemo.org. And it looks like they're ripping off some of the graphics (and probably some of the closed source bits, too) from maemo. I guarantee that it is the Hildon desktop, probably, as b-man says, based off of the Ubuntu variant, just like Mer. I'm sure that those are pirated icons used for OpenOffice, again probably from the Ubuntu armel distro. I wonder if the desktop icons are Personal Launcher?
