I have been out and about the past few days and not always had my camera with me, but my phone - of course! I often forget that it can be quite a useful camera and I have a bunch of apps for my phone that can turn nothing much into something quite interesting. It's also pretty easy to import your "app'd" images back into Photoshop and fiddle with them even further.
For these quick snaps I have used Pic Grunger and Swanko Lab apps. There are lots of variables to play with in each app, so you can really go to town and get some interesting effects on your image.
