Yup! They're pretty expensive to get the high-quality stuff, but they're really amazing. My friend back home is a specialist in making and installing them, and my brother has an arm and leg himself.

[It almost sounds like some sort of magic...but it very well might be something like that, with how wildly different all the worlds can be.]

Whatever makes it work must be pretty complicated, from the sounds of it. But it's lucky you guys are able to use them easily like that! I'm sure you'll get a lot better with practice.
