// Example 1: minimal constructor parameters
var ex1 = new SimpleMarker({
  position: new google.maps.LatLng(50.7572, 6.1453)
});

// The rest can be done through setter methods
ex1.setMap(maps[0]);
    

// Example 2: using CSS to style the marker
new SimpleMarker({
  map: maps[1],
  position: new google.maps.LatLng(50.7572, 6.1453),
  className: 'ex2'
});
    

The CSS class:
.ex2 {
  width: 16px !important; /** use !important if you don't want */
  height: 16px !important; /** to specify the 'size' parameter */
  background-color: #F00;
  border: 5px solid #00F;
  border-radius: 15px;
}
    

// Example 3: use methods to influence the marker after creation
var ex3 = new SimpleMarker({
  map: maps[2],
  position: new google.maps.LatLng(50.7572, 6.1453)
})

// I use jQuery to attach the events, but you can
// do that in any way you like
$('#ex3_visible').click(function() {
  ex3.setVisible(!ex3.getVisible());
});

$('#ex3_right').click(function() {
  var currentPos = ex3.getPosition();

  ex3.setPosition(
    new google.maps.LatLng(
      currentPos.lat(),
      currentPos.lng() + 0.001
    )
  );
});
