Google-maps – How to re-enable Pac Man mode in Google Maps

There is no events function in the Maps API. It's likely the site you saw was using another data source with the Maps API. What's the fun of a mashup if everything is in the same API? :)

Google Maps is not available for Google Apps accounts that were not created with United States as country of organization.

Unfortunately, it is impossible to change country to an existing account, you must delete your google apps account (wait 3-5 days for it to purge from google's systems) and re-create it.
