Three-Dimensional Abstract

[Pseudo Enigma]

I just discovered a lot of this awesome shit today. Wow. It seemed to be really popular around 2006/2007, and died off around then. For those of you who don't know, this is generally the trend I'm seeing with this art

Anyway, these pieces usually fell under the tag "3-Dimensional Art > Abstract" pool (or "Other > Abstract") on Deviant Art.

*hooked*
I kind of am really interested in looking farther into this. So the question for you, FFRtists, is

(1) Does anyone know if there is an actual name for this art style?
(2) Are there any resources available for learning how to do this crazy shit?

obviously, I don't want to outright mimic it, but it's definitely a field I've always wanted to try.

edit: I realize I might be posting a lot of different art styles, but I kind of wanted to grab a wide range of the style I'm talking about. Basically it's all that 3D metal crap in there. Last one is generally stock images thrown together, but I was thinking that probably had something to do with it.
