Good way to build a grid in Photoshop, Illustrator or InDesign?

[M A V I C]

I need to create a wall of video screens. Something along the lines of this:



If this were all flat it would be easy, but I need to add perspective. I know I could just adjust each image individually, but it would be much easier if I could just create a flat grid and then manipulate it as a whole.

What's the best way to build something like this?

Thanks.
