Also, if you are going for the "monsterous lecherous arm" there's the question of what's driving it. Is it just an expression of your own innate, repressed lusts, or is there actually an AI in that thing? If there *is* an AI (there's plenty of space in there to grow enough spare nerve cells to function as a structure) then is it just a singleminded impulse, is it more or less at the "dog" level, or does it have enough of a mind to communicate with? If it's got enough of a *mind* to communicate with, then does it, in fact, communicate? If so, how?
Completely aside from that, there's the question of how much control this impulse has. Obviously, in violent or otherwise critical situations, you have full control, one way or the other. Either you have control directly, or whatever it is that controls the arm recognizes the importance of the situation and lays off for the duration. Other than that, though, is it just a case of the thing wandering off on its own when you aren't paying attention, or do you have to struggle a bit? What if there's some particular person that it *really* wants to fondle?
Girl: "Rhodesu-sama? Is there something wrong?"
Rhodes: (Currently staring at The Hand, which is hanging in midair in front of him, poised to lurch forward onto the girl's primary reasons for preferring low-G environments, and vibrating with conflicting impulses) "No. No. Nothing at all. Whatever gave you that idea? Excuse me just a oment, would you please?"
For that matter, is there something in particular that people might do that would particularly attract the attention of the Hand? Do the fangirls know this thing? Likewise, is there anything or anyone in particular that the Hand is either completely uninterested in or terrified by? Why?
All of these are entirely up to you. There's no real need to even tell us what they are (though if you want to, I certainly wouldn't mind.) It may be that your character doesn't even *know* the answers to all of them. Still, I figure it might be helpful if *you* knew them. There's plenty of story-tidbit opportunities regardless, but you don't get *any* of them if you just leave it vague.
