I met Andy at MarCon '07, and the big thing I remember from the lecture was "With games you should either be able to ignore the game it isn't your turn (barring rule changes like limits), or it should always be your turn (he gave an example of a 'falling' game for this, but I don't recall what game it was)." Since that seemed to be Andy's previous intent for games, I would guess that the Catapult can only be used during the controller's turn.

I'm certain the intent is only during your turn. One of the unwritten design rules of Fluxx is that you can only play cards during your turn. (I pushed against this boundary with my own Keepers 16 Ton Weight and BBC Announcement which you could discard to invoke them while not your turn, if they were already on the table.)
The more I think about it though ... it's not playing a card per se, just using it ... hmm. Excuse me ...
Well, after looking at my decks I still cannot think of any official Keeper or Creeper whose behavior you can invoke outside your turn. The closest I could find is the Zombie Repellent, which would passively repel any Zombies you got outside your turn. So I'm reasonably certain Andy has never released an official Keeper that you use when it's not your turn. The "once per turn" phrase was to limit your use during your turn, not to expand its use to other turns.
TFOG, though, does seem to imply you can use it again and again during your turn. That's how we played it -- my daughter had fun doing just that.

Likewise, I think it's the Finger of God that lets you smite (discard)
a Creeper, and then it goes back into your hand. If the rules are
Play 3, is there anything to prevent someone from playing FoG,
discarding a Creeper, playing it again, discarding another Creeper,
and playing it a third time, then discarding a third Creeper, taking
FoG back into his hand and thus finishing his turn?
These are both FAQ-worthy questions. But however Andy rules, you could always make your own house rule to do differently.
