I'm looking for an icon for my new Android app, PixStack.
PixStack is a photo editing application. There are a number of available effects, such as grayscale, sepia, blur and threshold, among others. It's also possible to view the image histogram, adjust curves, view metadata, and print (via Google Cloud Print).
The icon should provide a clear indication of what the app does. Perhaps something that includes a photo, a camera, or a framed image. It should not, however, make any references to the name of the app.
The icon must be delivered in (and look good at) 36x36, 48x48, 72x72, 96x96 and 512x512. It should also follow the Android design guidelines (http://developer.android.com/guide/).
Finally, please integrate the text "Free" into a copy of the icon (which will be used for the free version of the app).
If you have any questions, don't hesitate to ask, Thanks!
