Custom Tile Layout

[Katalyst777]

For random, I would look at the Mosaic tile options.

You can copy the Mosaic material, paste it into -My Materials and then use the Adjust Material Definition (in 3D views also often called the "rainbow" tool) to increase or decrease its size. You should also be able to rotate its angle so that it displays as diagonal in the Adjust Material Definition dialog.
