Google Map - Flying Ladybug (US)
Link: http://code.google.com/apis/maps/documentation/
The code snippet below allows you to add a ladybug (or any other image), to fly over a map. The coordinate boundaries are for the United States (min_lon, min_lat, max_lon, max_lat), but you can change them to suit your needs.
After a random number of seconds, the ladybug lands on the map. When the site visitor moves the mouse over the ladybug, she will fly to a different, random point on the map. This continues forever. The site visitor will tire of this long before the ladybug does. 
This piece of code was named cartesian/optimize.js and included into page with a script tag. This allows you to quickly remove the code prior to deployment.
Recommended application … none. This is strictly for fun.
Code:
var bugIcon = new GIcon(); | |
bugIcon.iconSize=new GSize(32,32) | |
bugIcon.shadowSize=new GSize(0,0) | |
bugIcon.iconAnchor=new GPoint(16,32) | |
bugIcon.infoWindowAnchor=new GPoint(16,0) | |
var bugFlag = new GIcon(bugIcon,'cartesian/bug.gif',null,null) | |
| |
min_lon=-70 | |
min_lat=30 | |
max_lon=-130 | |
max_lat=50 | |
lat_range=max_lat-min_lat | |
lon_range=max_lon-min_lon | |
lat=(Math.random()*lat_range)+min_lat | |
lon=(Math.random()*lon_range)+min_lon | |
| |
var bug=0 | |
| |
function makeBug() | |
{ | |
bug=new GMarker(new GLatLng(lat, lon),bugFlag) | |
map.addOverlay(bug) | |
GEvent.addListener(bug, "mouseover", flyBug) | |
} | |
| |
function flyBug() | |

map.addOverlay(bug) | |
GEvent.addListener(bug, "mouseover", flyBug) | |
} | |

window.setTimeout("makeBug()", 25000*Math.random()); |
