Change your angle to the "amount.value * 100 / 50", and you should be
good ...
private function doSlide( event:Event ):void {
var distance:Number = amount.value * 100;
var angle:Number = distance / 50;
var rightMatrix:Matrix = new Matrix( 1, 0, 0, 1, 0, distance );
rightImage.transform.matrix = rightMatrix;
var leftMatrix:Matrix = new Matrix( 1, angle, 0, 1, 0, 0 );
leftImage.transform.matrix = leftMatrix;
}
