Just messing around with the new Create From Image tool in Photoshop (Find in Photoshop Libraries or see video below).
The top images shows what happens when I used the new tool. The bottom images is the original (source) image. The top images is what you get when you push the source image through the Create From Image tool. The Create From Image tool is perfect for making patterns, background images etc from existing images.
The the video below where Terry White talks about new tools in Adobe CC, including the Create From Image tool in Photoshop.
