It is an image processing application for texture/2D/UI artists. It removes redundancy from texture design process - you can add/remove/change/test anything, any time you want. There is no cost of reapplying filters or Undo/Redo usage - something you have probably fought with all the time while using GIMP or Photoshop.
You can see for yourself, there are screenshots and a demo version included.
Feel free to post critique and suggestions as they will help me improve the application.
P.S. Here's some screenshots of the app:

And here's the demo!
EDIT: I have never intended to give the full version for free and in case you see one who is uploading it, remember that what he offers is broken in all of the ways that you could imagine.
