Though we were quite silent for a couple of weeks, Rayne is far from dead and we are still working on it.
Also I wrote about our shadow mapping solution for the sun which is nothing fancy, but kinda production proven, stable and good looking at good performance: http://rayne3d.com/blog/05-18-2014-shadow-casting-directional-lights

About two weeks ago I also wrote about our clustered shading: http://rayne3d.com/blog/05-01-2014-clustered-shading-in-rayne

Oh and check out my Ludum Dare Game I made alone in 48h using Rayne, it isn´t too much fun and a bit buggy, but at least something and I ported it to Windows :): http://www.ludumdare.com/compo/ludum-dare-29/?action=preview&uid=35658

@the_clown: we do use STL quite a bit. Mostly std::vector, but also a couple of other types and functions.
