Mapping Events is a mashup of Google Maps and Eventful to display upcoming events by location.
You can search for events on the map by category, place and date. You can then sort the results by popularity, date, title, relevancy and venue. The results of a search are displayed directly on the map and in the map sidebar.
If you click on a map marker an information window will open with details of the event, including the date, time and venue. The window also includes a link to get further details from Eventful.
