If you've ever been to the Terminator 3D: Battle Across Time attraction at Universal, the video after the jump may seem a little familiar. Except the "Terminators" this time are bigger and more purple, if you know what I mean.
And there's also a whole lot more to explore if you follow the URL at the very end.
Check out the vid first, though...
