Zombies Solved!!!!!

I have been working for weeks, nigh months to figure out exactly how to convert the zombies for my Warhammer Vampire Counts army.. and I've finally had a breakthrough!!!
I had been toying with ideas ranging to something out of the matrix, like they had been implanted with something, or there were holes where something had been implaned or injected... here's a couple of research photos from then...

 But I wasn't sure how to make something like that read on the model, and on the tabletop... I'm also a big fan of easy conversions, especially on things models like zombies, where you're likely to have a lot of them... so then I thought, what if something that had been implanted hadn't been removed? What if there was like a warpstone fulled little power device (very similar to IronMan) just embedded in the flesh of this zombie? What if it was something like the Matrix, only instead of Jacking in with wires a thin rod of warpstone was injected directly into the brain?

Here's an example of what i thought by 'power source':

(the green thing in his chest)

Once again, unless it's huge, it would be really difficult to see... I still might do something like this, if I can get proficient enough with GreenStuff Modeling Puddy... something I am very trepidations about using... it's remarkably expensive! (for me :P)

So then I had the thought, earlier today: Throughout the army I'm using Warpstone as the power source that creates the steam that powers all of these insane inventions, in that context it's very similar to nuclear material. The thing is, I'm also still considering the fluff of the Warpstone being a foci for dark magic, as well as having the ability to, without direction, 'create' zombies. That's were the idea from earlier about shoving a raw hunk of warpstone into a corpse's brain and viola instant zombie!

However, if I was a vampire, and running my quasi mechanical army off of Warpstone, I certainly wouldn't waste it on a lowly zombie! And another idea I consitered, having the zombies just being a bi-product serfs dieing in close proximity to the vampire's forges, didn't seem to make sense because, on the battelfeild, Necromancers and Vampires have the ability to raise more zombies, no there definately needs to be some way of creating them.

That's where my comparison to nuclear material from above comes in! In a nuclear plant, the water that is heated by the neuclear fission into steam is used over and over again, eventually becoming extremely irradiated. If Warpstone does the same, the vampire would have a huge amount of Warpstone-infused water. If this material could be injected directly into a corpse's skull, between the skull and brain, i imagine the water would eventually saturate the brain and bam! you have a new zombie, ready to be bent to your will!

And when it comes to representing this on the tabletop... why, I almost wouldn't have to! If I do say so myself, it's quite subtle... if I wanted to though, I could always paint some blue-ish tinted veins on the zombie's skull, radiating out from the central point of injection...

I may still model something if I become proficient with Green-Stuff, however, this seems live a viable alternative... it's what I would do if I was a technology obsessed vampire :)

It also fit's with the model I was planning on using for my Vampire Lord (the model's Fabius Bile, if anyone was curious :P) He has that little injector-thing...
