It works by touching the screen in one or two spots move things around and it records your gestures for about ten seconds and if you let go of the screen it will continue to loop around.
It has a deep nice sound to it and would be well suited for recording sessions and then cut out the best parts. Can see it as a good companion to Virtual ANS for ambient excursions that can scare children, anxious old ladies and muscular men suffering from insecurity.
For free and no publicity!
