Here you can see the worlds first simulator with two rows with three projectors warped and edge blended from a single ATI card with six outputs with the only software, Warpalizer, that can do warping and edge blending on any number of rows and columns of projectors from a single PC.

The simulator is built by SimPit in New Zealand and uses back projection to get the tight construction and super high resolution. They also use a head tracker so that you can move around in the cockpit.
