This is a simple technique that can be interesting.
Take any of your photos; just one, and cut it into pieces within Photoshop.
Do this a couple times so that you have overlapping pieces in the same file.
This works well if you have a plain, solid-color background.
Set the blend modes to lighten, soft light, or whatever you like and drag the pieces around over each other.
Rotate pieces a little.  Make a composition and show your result if you will.

Here is a simple one I just did.  In this, all the pieces are squares and they're all the same size, but they don't need to be.
