On this timeline of all things google maps, I found a great application that lets you view live Seattle-area traffic data over google maps:
Seattle Traffic
For other cities, use this link:
Google Traffic
In addition to gHomes, some of the things that I thought were missing from the timeline include:
Both of these are awesome applications that are pushing the boundaries of making google maps easy and useful! Mygmaps is great in that it gives an easy to use interface for publishing your own information on Google Maps while dasnet is amazing in that someone is able to take tiles (from Microsoft’s terraserver) and post them in place of the gmaps times. Considering gmaps has the great interface, and terraserver has better quality aerials, this is a great service for all of us who love having high quality aerials at our fingertips.
