With Auroris you can create fascinating images directly on your iPhone/iPod/iPad, e.g. to use them as backgorund wallpaper. This is not a drawing app in the common sense. You are spawning glowing particles with your fingers that come to live by some kind of magnetic field. Have a look at the screenshots (number 4 and 5 are postprocessed) to see some of the results.
When youre satisfied with your creation, you can save the image to the gallery for further usage/processing.
Further planed updates:
*glow (since version 1.3)
-customizable magnetic-field
-support for logos and text
-music
