I was talking about Manjaro Linux. You can get it at manjaro.org.
GNU/Linux is free and open source software, which means that Manjaro can take what they need from other development communities and vice versa. The Mint community did a great job on making a GUI installer and a display manager, so Manjaro just uses those. Manjaro also uses the core system developed by the Arch Community, uses the email client and web browser developed by the Mozilla devs and community, etc... and the Manjaro development community then makes sure it all works together perfectly, and adds a few things of it's own (like the great update manager, tested update packages in their own repos, the incredibly great mhwd tools, etc...), adds some proprietary stuff that most home users want (proprietary graphics drivers for gaming, flash for internet entertainment, a preconfigured bumblebee setup for nvdia+intel laptop users, etc...), to come up with a stable, modern, pretty leading edge, traditional looking but highly configurable, very compatible distro, which they run on their own build of the linux kernel, and they maintain the whole thing and provide support for it. That's the way FOSS works, by leveraging community development, a small group of people can therefore deliver a much higher quality product than any closed source software corporation. The arch linux community is great, it's quite a achievement to provide a top quality bleeding edge independant GNU/Linux distro, and it's going stronger than ever before, but unfortunately, Arch likes to profile itself as an enthusiast distro, and for a beginner, I would not advise it, because it's pretty technical to do a full CLI install that is really optimised for your individual system, and the Arch support forum as a strong RTFM mentality, which is OK because their documentation is great, but a beginner doesn't always know where to start. That problem is complely solved with Manjaro. There are fora in all common European languages, and the community is very helpful, and the distro itself is very easy to install and use out of the box, and it will give you enough understanding about linux to become an enthusiast really fast.
Manjaro is just a project by a handful of young linux enthusiasts, but they take their distro very seriously, and even though it's still officially in beta (now at version 0.8.7, not that versions matter very much because it's a rolling release distro just like arch, so everyone always has the latest updates), it's already a solid distro with enough features for even advanced users to use it on a daily basis.
