The best thing for marines/chaos marines paper minis

I'm going to blow your mind for the most amazing and most detailed tool out there to make space marine paper minis. There's a Russian guy (at least I think he's russian?) who has made a program called Chapter Generator: an extremely advanced program which allows you to create a Space Marine (or even Chaos Space Marine) picture, complete with choice of current codex-compliant wargear. Each marine is mostly unique, as they are made from a pool of randomly selected pieces and a slider control just how much bling you want on them so your Sergeant up to Chapter Masters can look suitably over the top and overdesigned. Even better, this stuff include some vehicles, terminators and he's constantly upgrading the program to add new units and sub-factions (like certain Chapters/Legions and the new Primaris Marines).

Blood Angel, Space Wolf Corgi, Grey Knight, Salamander Terminator, Pre-Heresy Luna Wolf Terminator and a Thousand Son Rubric Marines. Next to these is a Primaris, but these guys are still a bit a WIP from the Russian Guy. These are all but mere samples as I've not shown every single feature, like Librarians, Chaplains or the usage of Mk2 to Mk8 armor for almost everybody but the Primaris and Chaos Marines.
