Unfortunately, two hands are required to play this game.
Really? Crap... now you tell me... =S
No wonder I keep getting killed...
--Snarky-ness Aside---
I'm not sure what 'Animated porm' mod the OP was referring to... but if that's your cup of tea, than Animated Prostitution has been out in its Beta form for a while now. Which is fine by me, since my first Fallout 2 character was a porm star and a hoker, to boot.
What? It payed for her jet addiction? Seriously...
I'm not sure about the other one you mentioned, though... 'the train one'? What one was this? Do you perhaps have any links to the original mod?
Overall, I'm pretty sure that... for any PERSONAL mods... you would be -capable- of porting over some of the building models and the like from Fallout 3. Just keep in mind that you're not allowed to POST any such mods, and to be entirely safe, you should probably avoid making much mention of it here on the forums. It's a violation of the terms of use and EULA and all that jazz.
But yeah.
Hope that actually proved to be a USEFUL answer. I know most folks here got so distracted by six that they forgot you were asking a question... but that just goes to show you that ToJka had it right.
Most humans are in heat, from adolescence till they die.
Pervy old men are the worst. I hope I die before I become 'that creepy old dude'.
