Bsbudd,
Careful! This stuff you posted a image file owned by Apple. Did you actually obtained the permission in doing this so. If you don't, don't even think about it.
Please kindly refer to Copyright-related topics, as it is pretty much self explanatory on your own. I am not fond of people when they proceed posting images of whatever stuff off the internet WITHOUT proper conset of permission in writing.
Yes, I know, people do it all the time without really realizing the consequence.
Best of luck!
I've made a video that might help with creating this effect using a scatter brush in Illustrator. http://upchr.ch/UZq0Mu
