Holy shit dude - what software do you do this with?? It's got to be hella complicated and expensive....
It's parametric and feature based modeling, sketched/drawn in one program and rendered in a couple of different specialized programs. "Complicated" is relative here - I'd say it's more about a dedication to put forth the effort to learn it and what you do with that knowledge once you've garnered it. You have to constantly challenge yourself in terms of how you think. When it finally clicks, you begin to see things differently (think "Limitless") and your understanding of most anything you see or can dream up in your head, changes.
As for cost, advanced CAD programs are very pricey indeed. But there is change in the air and one heck of a lot of innovation and creativity in terms of the future of modeling. If anyone wants to take a crack at it without emptying college fund accounts for the kids I suggest taking a look at Fusion360. It isn't what I use but I have it at my fingertips were I so inclined.

Carbon Revolution did a great job with this wheel and the technology and engineering behind it is truly fascinating. The people there and at Ford, working quietly behind the scenes on it, should be commended. The individual(s) that sketched the 2015 rendition of the snake should be credited as should those responsible for the badging on this car. It is sharp and minimalist - they absolutely crushed it.
Nice work. Can you get those made? FWIW I installed the thick gel decals with Ford logos on my wife's 2013 Fusion Titanium on the wheels, hood and deck lid and almost three years later they still look great. They changed the background from Ford blue to gray metallic to match my wife's car. So something like that might work. I can show you photos if you'd like.
There's probably a bit more detail than necessary for a simple centercap so a reasonable fascimile should probably be dumbed down and defeatured a bit for cost and simplicity's sake. I can hear the bitching already about having to use a toothpick/Q-Tip to have to clean up something such as a cap with this level of detail. Then again, life's too short so why not throw caution to the wind and choose badass over practicality? That said, sure this could be replicated.
I would be interested to see what you did Rick.
