Great concept!

This really is an amazing app- the possibilities are endless and with your picture and the stunning filters you can make digital art in no time at all.
Once I figured out how to load a picture from my photo stream I made some amazing images in minutes. Ever the digital obsessive I worked with the same picture with multiple filters.
Pretty amazing. Plus you can then take your finished piece into other photo apps to extend the possibilities.

Edit:
Still loving this app. So much creativity possible. There is only one frustration I have when using it. I wish you could save a version of what you are working on and then go back to do more to the same piece. Unfortunately if that is possible I havent figured out how. As it is if you save something you have to go back to your photo album and upload it and continue working on it. Which wouldnt be terribly inconvenient... Unless you want to undo a step on the version you saved and add something else. In that case you have to re-upload the original and go through all the different steps to get there again, if you can remember them. Or alternatively I guess you could save each step and then upload the one you want to go back to which is a very clumsy way to work.

Other than that the app is perfect. Sure, there are some other categories Id like to see, vintage ships or cars (horse and buggies?) vintage portrait photographs, and maybe a masking ability so you could add texture to just one section of an image. Still, its a 5 star app for almost any iphoneography artist.
Really love it for the range of possibilities!
