After a little bit of searching I found this photo of a guy jumping in the air by Camera Eye Photography. This is a great photo for this effect because the subject is in motion. So our dispersion effect will help to enhance that motion.
Copy and paste the photo into a new PS document. I sized mine down to 2500px wide. Using the Quick Selection Tool (W), I made a selection of the guy and copied and pasted him to a new layer. I then loaded the selection again, and with the background layer selected, I chose (Edit | Fill | Content Aware).
