Very quick Java app image overlay etc - $30

Looking at the Blackberry CameraDemo. JDE 5. What is needed, after a 2nd shot is taken. Make 1st shot image and the 2nd shot image transparent and blend them into one image and save it as a new image file. Delete last two shots and show this bended image as usual. On getting back to the preview screen reset it to take the 1st shot again..and so on. Other little works are about adjusting the UI a bit like, make the preview window bigger etc. but with that's with a lesser priority. You must be able to show a demo before hiring. Need this today,
