Marc Chung thought it would be cool if he had a map of the city he lived in, and it showed every venue and event that was taking place near him. Turning vision into reality, he got to work with the Google Maps API and created "Eve: The Exciting Venues & Events browser". It mashes up EVDB.com event listings and Google Maps to display a unique choose-and-view framing technique that allows you to narrow down your search in a very cool way.
The creator informs me that there are many US cities which have just been added to Eve and there are a few more features to be added. Check out this mashup in the making and give him some feedback!
