Give amazing Droste effect to your favourite photographs with Photo Spiralysis. It’s a nice tool which gives you the ability to use a spiral offset to create a spiral effect within your images.
1. Use the transparent part of a picture as the inner area
2. Supersampling around edges (reduces pixellated appearance)
3. Change the span of one iteration in a spiral (right now one iteration = 360°)
4. Multithreading (using more than one processor core to make things faster)
5. Using more than one source image
6. Automatically check the resolution of the source image
7. Creation of looping animations that zoom from one iteration to the next
