Picture viewer with metronome beat (OSX) (Adult Related)

****Programming for OSX – be nice to run this on Windows too, but not a requirement. Due to some of the requested outputs (text) and graphics to be used, must be comfortable working with adult related material**** Description: A game that uses a metronome beat and displays a series of pictures from user defined library. An interactive button forces the beat to change based on different mathematical and probability functions (already worked out). This was originally written as a script that ran inside of a Java based GUI. I would now like this to be a standalone program. I will provide the text dump of the script from the original as it has the correct logic and formulas.
