Kaleidoscope is on the App Store.
- Choose any photo in the library
- Shake to change position of the pattern center
- Drag with finger to change position of the pattern center
- Three rotation mode: manually, auto, freeze
- Scale up and down the pattern
If you would like to try it before buying it, you could download the free version “Kaleidoscope Lite”, but I strongly recommend the charged version, it’s much more fun to play with.
