Stargate: SVU gets busy with the body-swapping

Last Friday's Stargate had the first use of body-swapping technology as a plot complicator. For those who don't know what I'm talking about, they've got this alien device on the show that's kind of like a plug-in desktop Zen garden. You place a magic stone on top of this lighted box, and somebody somewhere else in the universe does the same thing, and just like that, you take control of their body and they take control of yours--until someone moves one of the stones.

There are lots of interest...
