I'm pretty sure the 'blue skin' part was a nod to Avatar. The concept of sliders interacting with a foreign dimension by adopting a suitable interface completely matches the system used in Avatar.
Hey! Take me with you to your world!Knew this would happen.And I'm fine traveling within the country ...*clatter*What is it like?
You have blue skin or something, right?So, you take a different form in your own world, right?Nope, it's pretty much the same.I can go to parallel worlds, but I don't want to go to one that's too different.Well, that's a waste!You can go to all kinds of worlds from there, right!?I mean, it's just like a regular overseas trip if the world is so similar!I'd go somewhere way different, if it was me!
