/// for the right side, the cube is turned 90 degrees clockwise around the y-axis
/// for the top side, the cube is turned 90 degrees counterclockwise around the x-axis
/// for the bottom side, the cube is turned 90 degrees clockwise around the x-axis

/// the rotations need to run in separate threads, because otherwise they would run in the UI thread
/// but because the events have to await until the storyboard finished, the rotation method's execution continues
/// so basically there is no way to wait until the rotation is finished in the UI for the rest of the methods to continue
/// therefore they have to run in a second thread, so that the event also runs in a second thread
/// the event handler can then synchronously wait for a task executed with the dispatcher to finish
