A look at Tanglu 1.0 'Aequorea Victoria' GNOME
Tanglu is a fairly young project and perhaps has flown under the radar somewhat. The 1.0 release is a major milestone for the distribution, which is based on a mixture of Debian Testing, Debian Unstable and in some cases even Debian Experimental.
However, as can be seen in the Tanglu FAQ, Tanglu is not designed as a "Debian experimental distribution or playground for untested software". Instead the project aims to "be usable for it's users and be released upstream software"; in other words, Tanglu strives to stick as close to upstream software as possible and wish to avoid "in-house solutions".
