I like to mess around with moving texture imagery using Adobe After Effects!  This mesmerizing effect was created from a simple shot of water in a swimming pool, shot on an iPhone in slow motion.  I try to avoid obvious effects filters, preferring to rely on layering techniques that go back to my pre-digital days on the Optical Printer.  The nice thing about digital, however, is that I can do something like this in a couple of hours instead of days & weeks!
