A friend posted this neat set of steps in Photoshop.  I suggest cropping to a square but rectangles can look good too. I have made an Action that you can add to Photoshop > Presets > Action.  It stops at the last step so you can still adjust the blending modes before Flattening all layers.  If you email me, I will send it to you.  susanbaileyphoto@gmail.com

1. _{Open you photo in Photoshop > unlock background}
2. _{Go to filter >pixelate >mezzotint >medium lines}
3. _{Go back to filter >blur>radial blur 100% >blur zoom quality best}
4. _{Repeat steps 3, 3-5 times}
5. _{Duplicate layer and turn duplicate layer off (eyeball)}
6. _{Highlight and work on original photo layer}
7. _{Filter>distort> twirl (angle value plus 80% or how you desire}
8. _{Turn on other layer and filter>distort> Twirl >Angle value minus 80% or as desired but it will be opposite of #7}
9. _{Alter duplicate layer blending mode to lighten on screen}
10. _{Experiment with other filter and blending modes}
11. _{Flatten layers}
