Don't worry - this is can also be viewed under 18, even though it's very sexy. Remmirath has posted an update about his spearheaeded project Elementalism that is in development for a while now with a lot of promising screenshots and some information about the development in general:

Back in October last year, GZDoom v3.2.0 introduced 'per pixel lighting' for models, meaning different parts of a model could be lit separately, compared to all-at-once like with sprites. This meant that, for the first time, models could be used as stand-ins for proper level geometry, opening up a possibility of vastly more interesting shapes and constructs than Sectors and Linedefs would allow. Unfortunately for the Elementalism team, we lacked any kind of real modeling skill, so we've been limited to simple shapes or pre-fabs. That is, until now.

What that means can be seen in the teaser for this news item. So what has changed? Read the rest of the post at the ZDoom forums. I really recommend checking out the rest and I wish the best of luck and dedication to the team finishing the project. It's simply amazing what you are doing here - keep up the good work!
