I am writing an interactive graphic novel and in the first chapter I show a summary of the protoagonist's childhood using static panels in a grid. The grid is white and the last panel marks the passage from static comic to interactive comic. I would like to turn the white frame of the last panel into white powder. Given that it is the only animation in the first chapter this single panel will appear on a separate page.
I would like to use the same effect for the chapters. The chapters will be numbered with Roman numbers in whithe color. When the reader touches the screen on swipes the Roman numbers the white lines will turn into powder and disappear from the screen.
Can anyone help me with that?
