Making dancing paint photos requires a lot of preparation, such as masking the workspace in plastic to prevent that everything gets covered in paint. You will have to dilute the paint for the right viscosity. Then find the right volume of the amplifier and the right frequency in the tone generator app. You will also have to clean up in between and afterwards. And clean up again,... You have been warned, it causes a lot of rubbish.
Check out this 'How to' page to see how this works.
