http://www.urbanexile.net - The newest site by Moridin. Similar to his previous site, it has a lot of cool 3D generated images interspersed with interesting and entertaining posts relating to all sorts of things.
http://www.moridin.com - This is Moridin's retired site. Despite no longer being updated, it still has some interesting 3D related info and tutorials.
http://joemills.com/ - Great blog of Joe Mills. He provides a unique (and very qualified) perspective into all things art related. Plus, he won't be afraid to stray off into media or other miscellaneous topics. Lastly, his main page also has some cool illustrations and designs of his own creation.
http://www.pivisuals.com - This is my site. You should already have it bookmarked. If not, then right now is as good of a time as any. It's all about the shameless self-promotion.
