Has anyone read "Hinterlands" by William Gibson (of Neuromancer fame)?
It seems like straight up a Pandora Gate set up, mixed with those pyramids on Giza, and is generally freaking spooky as heck.
Pseudopod recently featured it.

I thought it was really cool, and the sort of 'we must tinker with this despite it driving people insane' sort of set up reminded me of an even scarier Pandora Gate set up.
