Got curious and did some searching ... actually kind of suprised at some of the keyword domains for 3D that are not taken. The list below are all available as of this post, and all have exact match search volume worth noting (some in the tens of thousands of searches per month.)
Some points worth mentioning:
1)Wherever possible I used this hierarchy: .com, .net. .org, hyphenated .com (three words or less) .info, hyphenated .net (two words only) and then all other TLDs. So in some cases, if you see a .com listed chances are it's available in the other TLDs as well -- just didn't bother listing it for obvious reasons.
2) A lot of the search volume for 3D stuff is not so much about advanced technology as it is about currently-available 3D products. While not nearly as sexy as Chicks On TV That You Can Actuall Motorboat™ my feeling is that a person who wants 3D unicorn wallpaper and 3D art for his kid's bedroom ceiling is a natural foot traffic type for any other 3D stuff that comes out in the future. What I mean is, if you're serious about getting in on the "3D groundfloor" you might want to start with the existing traffic, not the future traffic.
3) I tried to eliminate all trademark domains and domains that contained trademarks in any context. Many are available in many TLDs
4) Ditto extreme adult stuff (incest, loli, that kind of thing.) No interest in reprinting them here, but they're out there if you want to go digging for them.

Ack, I'm tired. Also note:
5) "3-D" is a whole other realm of search. It doesn't get nearly the search volume as "3D" but it certainly gets enough to warrant attention. In a similar vein, the reason there are so many wallpaper domains is that "3D wallpaper" gets nearly a quarter of a million searches per months, which I thought was enough to warrant drilling down into the long tails a little.
