I took a photo of a metal grate at the base of a tree. I used various photo editing softwares on my iPod. An easy way to create a starburst texture.
I took a picture of this statue in Rome located at a castle near the Vatican. (the Pope wasn't available that day) Used a cool little app on my iPod to apply a filter, then transferred to my computer for more editing. If you don't like it, at least it's free.
